Defiant
« on: December 31, 1969, 06:00:00 PM »
Ball NPS Score: 100.00
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.

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.
