Title: Defiant
Post by: admin on December 31, 1969, 06:00:00 PM
HIGH PERFORMANCE
FEATURES:  
- Coverstock: MicroBite Solid Reactive
- Weight Block: Paragon Core (14-16  pounds)  
- Ball Color: Blue/Purple/Black  All colors do vary somewhat from the picture shown.  
- Ball Finish: 3000-grit Abralon  
- RG Differential: 16#-.052, 15#-.054,  14#-.053
- RG Average: 16#-2.49, 15#-2.49, 14#-2.52
- Flare Potential:  7" Plus (High)
- Recommended Lane Conditions: Heavy Oil  
- A few tiny pit holes in the cover stock of the ball are normal  
- Description:  At Roto Grip, we rule the  lanes! And you better have your game in gear if you want the same.  Starting at the center, the “GUTS”, the new Paragon™ core features  contours designed to help expand the RG planes of the ball. This unique  elliptical shape defines predictability of axis migration and allows you  to perfectly match up your ball reaction to the condition at hand.  Strong midlane roll and a HUGE continuous, sweeping hook on the backend!  This is a serious technological advancement.  Moving on to the shell, the “GRIT”, we’ve developed a new MicroBite  coverstock that is stronger and more textured than the competition.  Microtechnology, the use of extremely-small structured additives down to  a millionth of a meter, makes this possible. When finished with  3000-grit Abralon, this new MicroBite shell creates friction where  others just cannot!  And finally, looking at the “GRIME”, the designated oil pattern and lane  condition, the Defiant is sure to handle even the heaviest amounts of  oil. Today’s lane oils have more solids than ever before, making the  lanes very slick at times. With the new Defiant, no more worrying about  heavy oil often found on tournament shots! Roto Grip has you covered.

I got to throw this ball at the Storm & Roto Grip Open House on a 41' sport pattern ... the Defiant is sick!!! The new cover is so far ahead it's competition it just is not fair. And then I tried it on the house shot and could keep it from crossing over the face. As the day went on and the pattern broke down, the Defiant was not afraid to be pitched away from the hole and recover. This ball is going to fly off of the shelves.


Bakes...Before you throw my ball, know the holes aren't beveled!!!

New ball review for Defiant #1


Intended use: House patterns and future tournaments


Layout: 40 x 3 3/8 x 40 P3 hole—box condition


Well, I guess I should have expected almost starting against the ball return on a light oil house pattern. And WOW I was IMPRESSED with the way this ball hooks and knocks EVERYTHING down… It does not leave anything on the pin deck what so ever…  Great continuous arch and actually predictable down lane and does not hook early at all. Nice length down the lane and great back end reaction. This ball will be a KILLER on the lanes no matters if you are speed dominate or rev dominate…Used on HPL and SPL in different bowling centers and the results were pretty close, just had to swing it a little more on the older HPL. Practiced on fresh and well used lane oil and loved the ball in every situation. BY far the best ball Roto Grip has made since the original CELL.

New ball review for Defiant #2


Intended use: House patterns and shorter length Kegel patterns


Layout: 60 x 5 ½ x 60-- @4000ab and Polished


I wanted to create a longer length and a strong continuous reaction and this layout and surface change did the work. Once I noticed Defiant #1 start to move a little sooner on the lane, I will grab this one and tone down the speed a tad and work with it towards the same breakpoint on the lane. The ball did take to the shine quite nicely, and did not track up or burn up the polish even after about 20 games. I would say to keep it fresh I will re-polish after 25 games and resurface and re-polish again after 50 games. Maintenance is key to this MicroBite coverstock. Keep it clean and the ball will treat you right.

Lay Out: 5" from PAP at 60*    PAP  angle and 30*   VAL    angle. Dual angle measurement would be    60/5/30. The  pin   ended   up  1" above my ring finger with the CG  tucked under the ring finger. The 60* angle put the RG about an inch right of my thumb. This is a favorite starting lay out of mine for stronger pieces.

Surface: I am box  finish which  is 3000 sa-air abralon.

Purpose: I wanted to drill up this up to see what it rolled like and also to get it on the lane beside other pieces in my bag (higher oil volume-longer patterns).

Lane Condition   Observations: I have thrown this on a couple of different patterns: Left over shot the morning after a strong scratch league and all night open play, Highway to Hell-40 foot- Kegel challenge pattern, and second shift of our normal league pattern. The second shift was following a mixed league full of plastic throwers and head pin hunters. All I can say is I  love the reaction of this ball. Strong arcing but predictable would be the best way to describe it. Our house  condition is 38 feet on Brunswick Pro Anvil Lane. On the overnight leftovers, I had to start inside of 20 to find upfront oil to push this with and even then, it was still too early. On the Kegel pattern, this ball had surprising recovery down lane. Normally HTH is a medium volume but slightly flatter in the middle than most house shots. As long as I got it going with good direction and motion to my target, I had miss area right of the target by a couple of boards. I got to put it to use following the mixed league in front of us and this ball didn't disappoint. I left a couple of 9 pins late in the set, but was able to keep making 2/1 moves across the pattern and keep striking.

Response to friction:
I would rate this a medium  to quick response in box condition. The motion is strong and archy but not whippy off the spot. The response time  might go up some with a  smoother surface as this bleeds off a lot of energy in box condition.
 
Other Ball   Comparisions: I did get to throw it   some side by side with my VG Nano, VG Nano Pearl, Virtual Energy (2), and Nomad Dagger on the Kegel pattern. I played this little game of shimming 2/1 left every 3-4 shots with the Defiant and Nano. The Nano kept up pretty well until I got about 12/6 across the pattern. Then the Nano had too much upfront angle to carry the corners and started to ping half tens. I was about 4/2 right of my original starting point with the Dagger. I could hit the pocket with the Dagger at this spot, but not get much angle to get thru the pin deck very strong. The VE had slightly more motion but again was close to 4/2 right of the Defiant and bouncing off the pins slightly less than the Dagger but not getting thru them enough to want to start a game with. The Nano Pearl was the same look as the VE, then I hit it with a 2000 abr pad. This put the Nano Pearl about 4/2 right of the Defiant but the Nano Pearl was able to get thru the pins much better and also kept up going across the pattern at about 4/2 right of the Defiant. From these observations, it looks like the Defiant and VG Nano Pearl can be good compliments to one another in any bag.
 
 
Final        Thoughts: The Defiant has a look that is strong arc and reminds me of a couple of other real good sellers from Team Utah in the past (original Cell, Virtual Gravity). The motion is very unique and strong. I would definitely recommend one of these for rev-challenged friends in box condition. This will hook enough to get thru the puddles on any house league shot. Tweeners may be able to throw box if they are a little more speed dominant. Slower speed tweeners and high rev players may need to smooth the surface up to get the most out of the Defiant.

COMMENTS







Likes: I love this ball on a medium to heavy condition.  I was able to the ball through the heads easily.I
had my ball drilled with the pin down below the fingers.  (25
 X 4 ½ X 70 )This provided me with a
strong midlane roll and a very effective continuous, backend! I was able to
play 3-4 boards left of where I would normally play with the Critical
Theory.  One noticeable difference with
this ball is the way it takes out the corner pins.  Some of my in-between hits that would
normally result in a weak 10 pin are being tripped off. This gives me the
hooking power and reaction I need on the longer oil patterns.
 

The
Microbite technology coverstock gives me the look and the down lane reaction I
am looking for. With this cover I don’t have to worry about the lanes getting
burned up.  This ball gets through the
head and maintains its power all night long. What a great addition to my
arsenal. 
 


The
Defiant, Critical Theory, Shooting Star, Bandit and Outlaw provides me with everything
I need to handle most conditions.


 




Dislikes: Nothing so far.

     COMMENTS
     Carry - Since the ball picks up earlier than most, it gives a good  solid hit as it enters the pins. The arc shape of the roll keeps from  leaving those pesky 8 and 9 pins.
     Likes - Ball is strong and will be great on heavier oil when you can stay further right
     Dislikes - When moving deep with this ball, it seems that the ball  will pick up on the friction in the middle of the lane and have trouble  getting the ball to the right.
     
 I can see this ball being the ball that will make all of those people  who loved the original Cell run back to Roto Grip. The R & D team at  the Storm/Roto Grip facility has created another beautiful ball. The  problem with most new high end balls is that they absorb oil like a  sponge, and this causes a reduction in its ability to create friction.  The important thing for a ball now a days is not that it be dull, but  rather that as it absorbs oil and starts to shine itself up that it will  still turn the corner. As this ball begins to shine itself up, the  natural mid lane of the ball will keep the ball making its strong motion  to the pocket.

The Defiant is by far one of the best balls owned by myself to date. It reacts like no other solid cover ball ever put in my bag. There is a lot of big hooking early rolling balls on the market now days. But this is my choice over them all. It reacts off the spot extremely hard and doesn't tire out making the turn. Even when a miss right of target is put down the ball still finds a way to get back to the pocket and due to the way it retains energy so well most of the time it will kick the corners for me. Which is something I'm not used to seeing from my solid covers.

 

This ball will be great for so many. I'm a lower rev player and for me it was like being able to buy some extra hand. I'm able to move 5 boards further left with the defiant over anything else in my bag and still able to carry. It will also roll well for the higher rev players that like to play deep. Even in the fresh oil this ball will make the turn and knock ten in the pit.

 

This is the closest thing on the market for me that will retain the energy of a pearl and give me the earlier roll of the solid cover. By far the best ball Roto has made since the cell line.

Thanks for reading!

COMMENTS


Likes: The Defiant carries the corners like nothing else. it seems to give me one or two extra strikes per game, the weak 10 between the double and triple is now a 5 or 6 bagger. At first I couldn't figure out why but I think its the light particle load gripping the back end end giving less deflection and bite. This ball also revs up nicely and has a strong coverstock which gives you good angles into the pocket on medium to oily conditions.


Dislikes: Like all hooking balls, you need head oil. The ball started hooking slightly less and started leaving the 2 pin before i realized it was burning up early. I may have to get a second Defiant with a higher grit surface so I can keep this ball in my hand longer.

Ball specs – 15 lbs 2 oz, 2.86top weight, and 3 1/4-inch pin.


 


Using the dual angle method, the Defiant was drilled with a 4 1/4 inch pin distance, 75 degree drill angle and a 40 degree VAL angle. Using Strom’s drilling methodology the layout is 4 1/4 X 6  X 2 1/2  pin buffer. An X-hole was not needed. The surface was initially left OOB.


 


With a new cover stock formula (MicroBite), new core (Paragon), and OOB surface at 3000, the Defiant is Roto Grip’s most aggressive ball to date. If you have some hand or slower ball speed the Defiant will definitely need some oil in terms of length, volume or both. I initially threw the Defiant with the cover left at OOB and found it to read early on a 41 foot, 24 micro-liter house pattern. Even reading early the Defiant never stopped on the backend. I was very impressed with the tremendous hit and carry. I then hit the cover with Storm’s Reacta-Shine for the next outing. The cover seems very tunable and took the polish very well. (a polished Defiant looks great and would have great shelf appeal) The ball motion was very different on the same pattern. The Defiant became clean through the heads and had a much stronger move down lane. Hit and carry was again very impressive.


 


The Defiant is a very strong ball that has more overall hook than the Theory. The OOB cover will benefit speed dominate or low rev players or play well on oilier conditions. Don’t be afraid to add some polish for more length and a stronger backend move.

Hand: Left

Ball Speed: 16-17mph

Ball Weight: 15lbs

PAP: 5 left 7/16 up

Degrees of Tilt: 17

Layout: 5 x 3.5 x 3

I drilled the defiant with the pin above the bridge and the mass bias  an inch away from my thumb. The ball gives me a clean read through the  heads with an even back end reaction. The defiant is a great all around  ball for many types of bowlers. It is not a big flip ball so you can get  a lot of control and it does not lack on power on the back end for a  even ball. I did not think the defiant was going to be stronger than the  Virtual Gravity Nano, but once I compared the two I got about 4 to 5  boards more recovery with the Defiant which was really surprising. With  the way the ball is designed it is driller friendly so you can use your  favorite layout with no problem. The first night of league with the  defiant I shot 747 with the factory surface on it. If you are looking  for a ball that is an overall strong ball this is the one for you!

I have a video on youtube and a picture of my ball and the  layout on facebook. If you have any questions about the Defiant email  me at grichardson7716@aol.com.

I was so excited for the release of the Defiant I preordered 2 planning on having a ball for THS and a ball for Heavy oil. All I can is WOW! I loved the Cell when it was released i have a majority of my award scores with it. I know the Defiant is going to be a producer for sure.  I don't know the drill specs(one drilled pin up the other pin down) but I'm a tweener in the 16-17 mph range with a rev rate around 300 and a 50-60* tilt.  (pending how you look at it.)

 

Throwing the Pin up on Tuesday it is a joy to throw. When the team you're bowling against says "wow we're in for it tonight!" you know it's a great ball. I started in factory hoping it would Handle our WET/DRY house condition effectively.  the 3000 Abralon grit was a bit much as much as i hated the thought of polishing it. I was anxious to find out. after a 215 game start I added some luster and the Defiant started doing things i've never seen before. Never have a seen a strong ball so clean through the fronts and go on a rip-n-tear mode off the break point. games of 247 and 258 to close out the set leaving a blowout 7, (2) Blow out 8's, (2) blow out 9's one of which the 6 pin moved the 9 pin nearly to the 8 pin spot. DEVASTATING!!!

 

This Ball Flat Out Rocks!

Layout on the ball is dual angle layout 45x4.5x60 with a balance hole down.


I am a left handed tweener with a 325 rev rate.


This ball is the next great high performance ball from Roto Grip. This ball is very continuous on the backend. It really does not stop. It goes through the pins with ease. This ball is perfect for longer/heavier patterns. Even with the strong backend, this ball clears the front very well. I have used this ball on heavier house patterns and sport patterns.


 


I have tried this ball at multiple surfaces, and it has shown me that it is very versatile. This ball shines up well to get through the heads and save energy for maximum backend reaction. Even at 1000 grit, it still cleared the heads and continued on the backend.


 


This ball is a must have for your bag. Who doesn’t need a ball that will hook on anything?

Defiant Ball Review.

 

 

 

  I drilled this marvel with the pin in the center above the fingers with the CG in the center of my grip with the MB kicked out slightly.  I use this drilling frequently for league as it tends to work well on my THS (Typical House Shot.) Using the box surface with no alterations I anxiously pulled it out of the bag for league night.  I was pleasantly surprised at how stable this ball rolled mostly due to the core design.  The longer I left the Defiant in the oil the harder it seemed to hit.  With ample oil I have yet to shoot under 250 with this ball when I am able to use it. Sometimes, as with many high performance balls there is simply not enough oil to use it before it “burns up.”  This has become my benchmark heavy oil ball.  In summation, I strongly recommend this ball from intermediate to advanced players looking for a better look on heavy oiled/long pattern lane conditions.

Likes: The Defiant is one of the strongest balls that I have used today.  It rolls very smooth and allowed me increase speed and play the track area on my local house shot.  I was also able to use this ball at the Cheetah Championship in Fountain Valley, Ca.  It was a little strong to start but was an absolute Killer once the pattern started to carry down.  It gave me smooth transition a strong roll and drove through the pins like a mac truck!  This ball is a must for anyone looking for a smooth rolling ball on heavy oil!

COMMENTS



Likes: Where do i start. First, I want to thank roto grip for stepping up their game once again. I absolutely love this ball. I went with the 5*4*3 layout because I have personally seen how strong this ball is on the backend. Well hats off to roto grip!!!!!. The MOTION of this ball actually surprised me far greater than any ball. From where I throw my nano, I am 5 boards left with my feet and actually getting the ball out further and my nano has a stronger layout. .......I should add that I am very consistant at hitting both my mark and my breakpoint. And from that comment i want to add that I noticed on shots which i would pull, that this monster would actually hold itself as if there was no bridge keeping it from jumping over to brooklyn.. I sliped miserably on one shot when i was throwing over the center arrow out to 8 and actually went over 18 and out to 2 and this unheard of specimen called Defiant actually had the nerve to go back to the pocket. Another thing that i have noticed, is this ball doesnt do what normal balls do when the oil starts moving. what i mean is my solid balls such as the cell, VG, and  VG nano immidately start punishing me with splits when my line starts burning up. but the defiant actually started leaving me with 9 pins and as soon as i would notice that 9 fall last i adjusted a normal 2-1 and the ball continues doing its thing.. that is all that i have to say about this ball at the moment, i shall continue this review whenever i get to throw it on some sport patterns within the next few weeks. I think i will add a video as well

Likes:I really like the Backend motion on this new release. When it makes the Turn there is no stopping this ball. I have had the ball for a few weeks and missed an 800 last night by 32 pins. Went 278, 276 then 214 as I failed to move soon enough. I think Roto Grip did a great job on this release... Now maybe a Pearl with this core? ;)


Dislikes: Those pesky nine pins.....Ball is so strong it continues driving through the pit. Not really a dislike though :)

I picked this ball up a few weeks ago and was expecting a lot.  The ball seems to work great for me on a typical shot, but when I find heavy oil or heavier mid's, it doesn't react like I thought it would.  I wish it would turn the corner faster/harder for me and it's not.  The pin action is good, it does have drive to the pocket and the pins do explode.  I'm averaging probably 220's with it, but it seemed to be harder than easier doing it.


 


I'll post additional posts in the future after I put additional games on it.


 


Thanks...

HERE IS MY LATEST DEFIANT REVIEW
DEFIANT #3 – 50 X 5 X 55 PIN ABOVE THE MIDDLE FINGER AND THE MASS IS LEFT OF THE THUMB AND THE CG IS OUT AT TO THE LEFT OF THE CENTER GRIP LINE




INTENDED USE FOR HEAVY OIL SPORT CONDITIONS WITH DRIER BACK END




TEST BALL ON TURNPIKE, DEAD MAN'S CURVE, AND AUTOBAHN AND A THS




FOUND THE BALL TO ROLL QUITE NICE ALL THE WAY DOWN THE LANE, IT WORKED TO MY ADVANTAGE TO HAVE THIS ONE LAYED OUT THIS WAY AND ANOTHER DRILL WITH A LITTLE MORE BACKEND IN IT. I ENJOYED USING THIS BALL ON SOME FRESH HOUSE SHOT WITH A LITTLE GRITTY LANE PANELS AND SUPER SLICK PANELS. THE BALL PATH WAS NICE AND CONSISENT AND NEVER SHOWED SIGNS OF ANY OVER/UNDER REACTIONS. ONE THING I DID FIND AFTER PLAYING THE SAME TRACK AREA ON THE SAME PAIR OF LANES AND TRANSITIONED TO THE POLISHED PIN UP DEFIANT I HAVE AND CONTINUED TO PLAY THE SAME AREA

MY LATEST DEFIANT REVIEW

 DEFIANT #4 – 50 X 3 3/16 X 70 PIN DOWN AND P3 HOLE AT 2000Ab

INTENDED TO REPLACE A THEORY I HAD TO REPLACE A MUTANT CELL I HAD OVER 300 GAMES ON IT

TESTED ON 4 DIFFERENT HOUSE PATTERNS WITH WOOD, HPL, SPL, AND PRO-ANVIL

USED MAINLY ON HPL AND SPL FOR HOUSE PATTERNS ONLY. MY CURRENT BENCHMARK BALL. I FOUND THIS BALL BE HAVE THE MOST EVEN AND CONSTANT ROLL AND HOOK I SEEN IN AWHILE WITH A PIN UNDER DRILLING. ITS STRONG ENOUGH NOT TO BURN OUT IN THE FRONT PART OF THE LANE. I START WITH THIS BALL AT 3 OF THE 4 CENTERS I BOWL AT ON A WEEKLY BASIS. I SWITCH THEN TO A PIN UP, AND THEN TO A PIN UP POLISHED VERSION OF THE DEFIANT.


THIS IS MY 4 DEFIANT I HAD DRILLED AND ALL OF THEM ARE WORKING TO THEIR INTENDED USE. MOST VERSTILE BALL I FOUND SINCE THE ORGINIAL CELL.

BALL REACTION

I am doing this review on two Defiants. 
 
The first Defiant I drilled is the 4 1/2 layout.
 
I chose this layout as it is one of my favorites, putting the pin in the ring finger. The Defiant is a very strong, high end bowling ball, and it shows. With this layout, I can see the early reading motion, with a strong, yet controllable back end motion. The only thing, since this is a stonger layout for me, is that the ball had a tendency to use its energy to early and hit a little weak. After applying Storm Step 2 to the surface, I can get the ball to clear the mids and store more energy. Instead of putting the ball away after a game and half in league, it now can survive the whole set hitting hard. The ball definitely needs oil, especially in the heads and mids. If where you are bowling at is lacking oil early, shine the ball to get it to retain energy.  
 
The second Defiant I drilled was designed to clear the mids, and not have the issue I saw with the first one. This layout really gets the ball to clear the mids, and makes a real strong, late movement on the lane.  I saw exactly what I was expecting out of this ball. It is unreal to see how much potential this ball has in the back ends.  With how much this ball corners in the back end, I am able to play a different part of the lane and stay away from others in the track area. This Defiant is easily 3-4 boards stronger than the first one, since it stores its energy much longer. I do not see the loss of energy that I did with the first Defiant, and will not be shining this one unless needed to for tournament needs. 
 
With how strong of a ball this is, I recommend drilling this ball to store energy, as some house shots do not have enough oil for this ball. Do not be afraid to alter surface either, changing surfaces on bowling balls can make a huge difference on a ball, whether it is hooking too much or not enough. 

 
COMMENTS

Likes: Great ball, strongest ball out there. Great for lots of oil.

Dislikes: None, tweak the surface if needed.

I purchased this ball (suggested by Pete Somoff) to handle "thick and slick" conditions - this ball does not disappoint!  It has a nice arcing motion, yet is fairly forgiving.
 
COMMENTS

Likes: Really holds the lane and cuts through the oil extremely well.  Great on fresh oil, especially if it's "thick" in the middle.  It handles "long" patterns well.

Dislikes: This ball DEMANDS OIL! "Short" patterns and dry/burned-out conditions will force you to put the ball back in the bag - the cover is that aggressive!

 
SUMMARY
If you need a ball that will hold the lane, yet still retain hitting energy with minimal "over/under" at the breakpoint, this ball should fit the bill.

Left this one dull – Pin 5x5 above ring finger, MB right of thumb.


 

With this drill pattern the ball rolls very strong at mid lane. On oily conditions it is AMAZING. It reads the mid lane and does not skid through the break point and it hooks all the way through the pins. On some drier conditions it will slow down on the back ends but then I just moved deeper. I was able to keep my speed up and have a ton of hook with this ball. The design of the weight block allows the ball to recover itself on my errand shots. This is a must have ball for oil and if it’s not oily enough it shines very well. See my review of the Defiant #2.

Shined 4x5 – Pin below ring finger.


 


After using a dull one I had to drill another and shine it. OMG, this ball shined is out of this world! I put the pin below the finger so that the ball would not squirt past its break point. This ball is very good through the fronts and very angular in the back ends, which made my carry go way up. The day I drilled it I bowled 857 in league and physically did not throw it great, but it made my bad shots even look really good. My biggest love of this ball is how it makes up for human error so much better than any other ball I have. This ball is super bowler friendly for those who aren’t perfect every shot.

COMMENTS


Likes: First, would like to thank Mike Sinek with Roto Grip for helping get this ball. Based on my ball speed, and the fact we began the Shark pattern, my driller and I decided to go stronger with the drilling on this ball. WIth my speed, I don't usually have an issue getting the ball down the lane, especially on Shark. The Defiant has a much different shape and is overall stronger then a Nexus (P+F) drilled similar. I found this to be the strongest ball I have thrown. It's has a good read in the mid-lane (hence the 3/10 on length, the ball reads the mids very well), and allowed me to attack the Shark pattern from an inside line, something I have had difficulty in doing prior. And even with the mid-lane read, the ball doesn't lose energy in the back part of the lane. It continues through the pins and allows good carry even from the inside angles of Shark. Overall I am very pleased with this ball, and it is the first ball out of my bag on Shark, and will continue to be on any longer, heavier pattern. If you are looking for a strong, controllable ball with a nice arcing move, this is the ball to get. I have yet you see it where it drastically over-reacts coming out of the oil.


Dislikes: The only dislike I have is that the cover seems to get an oil shine to it very quickly. But with proper cleaning and maintenance, it hasn't been a huge issue.

COMMENTS

Likes:  Predictability, pin carry, ball motion

Dislikes:  None

Where do I start than other to say this has to be one of the best heavy oil balls that I have had a chance to throw.  Stats: 19-22mph, 380-420 revs, low track.  Bought with a 3" pin to CG distance, I used a pin down, 3-1/2 x 5 x 3 layout  to accomodate my speed and also give me flexibility on a wider amount of conditions.   I also wanted to have the ball pick up the midlane earlier.  This layout was the jackpot for me.
 
In the house I bowl at, we use a heavy 43' house shot and typically have clean backends.  Using my A game of playing outside, this ball is a perfect match.  If I threw a little too far out, the cover is strong enough to make the turn and come back.  If I pulled a shot, the ball is forgiving and held in the oil without overreacting.  I was absolutely locked in and was not missing the pocket.  Carry is excellent where pins stay low and had virtually no deflection.
 
When I moved inside, I found that the Defiant is just as predictable.  Slowing my speed down a little bit, I found that the Defiant worked equally great.  If I went slightly wide, the ball still made the turn and could hit the swish zone without any issue.  If I cut my swing short, the ball would hold without overreacting.  Again, I found the carry to be excellent and virtually no deflection.
 
Now, this ball does need oil.  Once the lanes transition and the Defiant hits the dry, it will definitely hook a ton.  No questions asked on that.  With the transition, be prepared to move deep, or go down to something weaker if you want to keep a similar line. 
 
Compared to my Virtual Gravity Nano, I found the Defiant to be as strong or slightly stronger.  The 3000 grit MicroBite cover and Paragon core are a great match, and fit my game better.  The Nano with its 4000 grit NRG cover is good, but was hit or miss at box finish.  Sanding the Nano to 2000 grit and redrilling to the same layout I used on the Defiant helped me be more successful. 
 
I also like the predictability this ball offers.  While the Nano tends to go a little longer and be more angular in the back, the Defiant will pick up the mids a little earlier and give a consistent hard arcing layout.  I also found that it stores energy better.  It reminds me a lot of the original Cell, but stronger.
 
This ball has to be one of the best that Roto Grip has ever produced.  The cover/core are a perfect match for each other.  It fits a wide variety of styles and is versatile with surface changes and layouts.     
 
Bottom line- if you have a Nano but want something more predictable and forgiving, the Defiant is the answer.  If you have never thrown Roto Grip before, and need a heavy oil ball, this ball should be on the short list for your arsenal.  You will not be sorry that you bought one.

COMMENTS

I don't want to sound cliche but will say this ball is quite strong.  It has a lot of backend motion for a heavy oil ball.  I like to compare it with the Critical Theory since I was very impressed with the hook potential on that ball.  The Defiant is several boards stronger but with a different shape ball reaction.  While the Critical offered good length, good midlane read, and a very defined transition from hook to roll, while producing a heavy roll...the Defiant offers relatively good length, a better midlane read, and a smoother transition from hook to roll, while also producing a heavy roll with very good continuation.
 
The ball is more at home in longer or heavier patterns, as you can imagine, but if you have lower revs or higher speeds, you will get more mileage on medium conditions.
 
I am a lefty power stroker and was able to just keep moving deeper and the ball continued to drive hard into the pocket.  I finally got as deep as 24 to 8 on the longer 42ft pattern and finally left a 7 pin.  Normally I don't have to get that deep, but was testing it out. 
 
Our stroker tested the ball on 38 ft THS and Viper, but would also rather throw the ball on heavier or longer patterns.

Likes: For Me a low rev bowler, I picked up this ball to fill the void for my Heavy oil spot,

I drilled the Defiant for Max hook, 1st time out, the ball rolled well for me, where my 


Yeah Baby and Prodigy would sometime glide passed the head pin this ball picked up and


rolled, I love the Matte finish which I kept at box 3000 abralon, I have low rev's so, for me the 


ball was clean thru the fronts, and was getting to the pocket consistantly.  I moved 3 boards 


left from the 1st game to the 3rd, I have never done that before, but, I made the adjustment and


finished strong.  I am looking for good things going forward, this will be My benchmark ball and


I will adjust from there. 




Dislikes: None so far..

Likes:The new Defiant has lived up to all early reviews on the left & right side. As a Senior Lefty Stroker I found the ball is super both dull & shined...My dull ball has a 3 inch pin below ring finger & CG is kicked out 1 inch. My polished ball has the pin 1 inch left of ring finger..On house shot the shine gets the ball out & down lane on the dry with a strong back end. 3 700's in 1st 3 weeks of use. In a local Senior 9 game tournament changing lanes each game I used the dull box surface. I was able to stay in the oil & go straight up 12-13 and the ball went long with a smooth back end to the pocket & 10 in the pit, as a 290-2310 total for the win can attest. All other lefties were out in the dry & left lots of 7 pins...Larry Hoffman, RG Advisory Staff..

Likes: The Defiant was very clean through the fronts for a strong Asymmetrical Ball.  But it has very good mid-lane read and doesn't squirt through the break-point.  The Defiant showed its strength on our house shot when the backs very not very clean and had some carrydown.  The ball didn't wiggle down lane like some balls would.  We have over a 100 units of oil in the middle part of our house shot and defiant cut right through it and had a strong arcing motion on the back.  Feedback from our customers was that they were amazed with the great carry they got from the Defiant.
This ball is will fit all styles of bowlers as the coverstock is very versatile.  Along with the ball being driller friendly.
The high rev bowlers will have to add step 2 or some light polish.
 
Compared to Virtual Gravity Nano, the Defiant is cleaner through the fronts and has a little more backend motion.
Defiant is another great product from Storm/Roto Grip Family.

Hello all and thanks for reading.  This review is accompanied by the the following video: http://www.youtube.com/watch?v=ExRr2D5EhFU&feature=relmfu
 
So those of you who don't have a Defiant,.....  well..... WHY NOT!!!!   This ball is absolutely amazing.  Hitting Power, Hook Potential, Core, Coverstock. There is nothing about this ball that should be taken lightly.  The new MicroBite Coverstock in combination with the new Paragon Core allows many options not to mention how well this coverstock takes to surface changes. 
I decided to use a drilling that I enjoy and modify it a little bit.  70 x 4 7/8 x 60.  This drilling allows me to use it on some of the more medium conditions and play the middle more effectively.  Make no mistake though, this ball enjoys oil and make bowling on the heaviest of conditions much more comfortable.  You can see in the video this ball picks up in the midlane and begins rolling right in the middle and does not need the lighter parts of the lane (outside) to start its move.  On the backend is makes its move and starts rolling forward providing excellent hitting power and continuation through the pins. 
 
I have enjoyed this ball so much I have 3 now.  Three different surface, with three different drilling patterns that I have experimented with and can use all varieties of surfaces on all of the drilling patterns.  This ball is quite literally confidence in a box and our pro shop hasn't drilled one without rave reviews yet.  Keep the Great work up Roto. You are truly the King and you have the most Defiant man in the world on your side.  Thanks Randy

Roto Grip Defiant #5         serial#12RDED03K013      layout: 65 x 5 ½ x 40 
Drilled this Defiant to compliant my two new EDGES and my new Critical Theory I drilled for the upcoming tournament season. Mainly, did this for longer sport patterns I will be seeing. Tested on Dead Man’s Curve, Highway to Hell and Mexico City on HPL… Found the length and the hook angle ideal for these patterns, the ball was too strong on HPL house and on the SPL house pattern it was MONEY… Love the length this layout gave me, it did not burn up in the front part of the lane on SPL and still had plenty of backend and pocket angle. I drilled a number of these balls for some of my customers at HBC in Hanover, because the SPL is new and the lane pattern is super tight. If you bowl in a center with a tight house pattern, this BALL is for you.

Roto Grip Defiant! This ball is amazing! I bought a used one for $30 in pretty good shape. I was looking for a cover that likes to dig into oil with a core that revs up quickly without burning up. This ball does exactly what I was looking for. Being that I have a high Rev rate (550+) and high speed, I am able to use this ball on any condition with a decent amount of oil. The continuation on this ball is disgusting! it reminds me of my favorite ball Danger Zone HPD. If you need a ball to control the oil without an overwhelming amount of hook, grab a Defiant!
