Sigma Sting - #Strikeupabuzz

The original Sigma Tour was my initial MOTIV piece drilled as a MOTIV Staffer. The NEW Sigma Sting represents a different reaction despite using the popular Fusion Pearl Cover combined with the reliable constant motion of the Sigma Core.

Although the Sigma Sting uses the Fusion Pearl Cover, I wouldn’t characterize the ball as having an angular motion. Even with the low RG (2.47) core, it still gets plenty of length with the out of box surface (1500 Wet Sanded/Polished). This time the #redball cover provides a very continuous motion that makes the Sigma Sting very distinct.

In comparing the Sigma Sting to MOTIV’s previous release the Cruel Intent, the Sigma Sting doesn’t provide as much over all hook. For me the Cruel Intent allows me to play further in and exits the pattern more forward than the Sigma Sting. Next, the Tribal is much cleaner and has a much more pronounced backend compared to the Sigma Sting. You can see in my video how each ball actually differs and will notice how different the shape is for each ball.

I currently have two Sigma Stings, one pin up and another pin down. The pin down Sigma Sting is noticeably earlier and stronger overall as it should be. The pin up is obviously cleaner and stronger downlane, but the similarity between the two is that they both see the same continuation throughout the roll phase.

This will be a benchmark ball for anyone, both of mine are still benchmark balls even with the different layouts. The Sigma Sting it is plenty of ball to throw on the fresh, but is clean enough and can corner with deep angles on a lighter or broken down conditions without over reacting. I have thrown it on several occasions on different patterns and I know we can all tell right away how much we like a ball, well this one is sooooo good!

    Opening Thoughts

    The basics on the MOTIV Sigma Sting : MOTIV has finally put a pearl coverstock on the popular Sigma core. The ball is a fairly medium revving ball ,that gets good length through the heads with a long and continuous movement to the pins. It is the longest continuation I have ever seen from a MOTIV ball. Lengthwise it compares to the Thrash Frenzy but more aggressive at the breakpoint. and more continuous.

    The Sigma Sting fits somewhere between the Primal Rage and the Thrash Frenzy.
    One of the nicest things about the Sigma Sting is that it performs well on such a wide variety of conditions .And works well for a lot of styles.

    The Sigma Sting has all the features that make a ball great. It is predictable and keeps you in control of your breakpoint. It has a strong enough movement that is arcing and continuous without being uncontrollable. Yet strong enough to allow bowlers to open up the lane.

    In 2011 MOTIV produced one of the best control balls ever.The Sigma Tour.It was one of the most predictable balls made.
    Now MOTIV has updated the Sigma line with the Sigma Sting. They took the popular Sigma core and wrapped with the Fusion Pearl Reactive coverstock.

    On the oil,a condition that that you would think wouldn’t be a strong suit for the Sigma Sting,it performed very well.With the heavy oil in the fronts and the fresh backends,I saw nothing but positive things. It navigated the heads with ease and turned up the revs late in the midlane ,showing no sign of squirt or jump at the breakpoint.When it encountered the dry at the breakpoint,it never overreacted,it just went into it’s long continuous movement to the pins. The breakpoint was always predictable.The ball reacted to the way the bowler rolled it.
    When the heads got spotty and the carrydown became evident, it just took a simple move left to adjust for the angle to the pocket.

    On the blend and breakdown condition,I still had plenty of oil in the heads left ,but could now bounce it of the dry downlane without overreaction.This is where the longer continuation helped.I never had any fear it wouldn’t recover.I now could confidently use the length of the ball to get it through the heads and around the pattern without fear of it burning up to early and hitting weak.The pin carry was still good.

    When the lanes became fried and the heads were gone and the pattern blown up,it was time to put up the Sigma Sting,and pull out the light bulb core of the Tribal.
    The Sigma Sting is very user friendly for all styles.The power player will be able to use drilling and surface to get even more length so the ball can use it’s powerful,yet predictable backend movement.

    The Tweeners will be able to increase their hook potential at the breakpoint,but still allow them to play more down the boards.Yet still have a ball to help them open up the lane.

    And the Straighter and speed dominate style players will be able to drill it up stronger and still stay in their comfort zone.And have a little more hit and carry from the outside angles.

    The Sigma Sting is not the strongest ball in the MOTIV line, but it is a ball that will allow you to go to it with confidence.

Likes: This ball responds extremely well to all of my physical adjustments. From lofting, to hand position changes, and ball speed adjustments. It can be used so often and is incredibly versatile. It is that trademark heavy mid lane roll that MOTIV is known for, but also offers outstanding continuation through the pin deck.

Dislikes: It is really hard to point out any dislikes with the Sigma Sting. I have quickly fell in love with it. It has potential to replace the Primal Rage as my favorite bowling ball! Drill one up for that ideal "benchmark" ball that every bowler needs.

Drilling:  Pin up above bridge

The Sigma Sting is one of those balls that once you start throwing it you will have a hard time putting it down.  The Sting has decent length and loves to start to rev up in  the mid-lane with great movement through the pins.  The Sting has quickly become my benchmark ball as I can use it on most patterns.  What I love the most of the Sting is its ability to open the lane patterns up and find its way to the pocket.

The Sigma core is back and better than ever!  Wrapping this award-winning core (2.47 Rg, .047 Diff) in the potent Fusion Pearl coverstock (finished at 1500-grit) has provided the market with one the best benchmark balls that anyone can have.  I drilled this ball to give myself a perfect compliment to my Primal Rage, especially knowing that the only difference between the two is the engine inside of them.  While the Rage effortlessly glides down the lane and then unleashes a fury on the backend, my Sting gives me a slightly earlier read and a more controlled motion at the spot without sacrificing any hitting power.  I have found so far that it does not matter what angle I am playing, the Sting reads the lane beautifully and still drives strong through the pins.  I have been able to move as much as an 11-7 from frame one to field ball game three and not have to worry about whether this ball was up to the task or not.  If you need versatility in a ball that is also the perfect benchmark for your arsenal, look no further than the Motiv Sigma Sting.  Strike up a buzz!

The Sigma Core really put MOTIV on the map a few years ago when it first came out. Due to the core’s versatility and predictability the original Sigma Tour was the “Go To” ball on tough tournament conditions for competitive bowlers. MOTIV took this popular, proven core, and paired it with what most would say is the most successful cover to date (Fusion Pearl Reactive – first seen on the Primal Scream) and you have the best of both worlds.

I drilled my Sigma Sting with my favorite layout, 60* x 5” x 40*.  I am a somewhat rev-dominant player, with a rev rate of 400, and a launch ball speed of about 18mph. The first thing I noticed is that the Sting was stronger than I was originally anticipating. In fact, for me, the Sting hooked 3 to 5 boards more than the Primal Rage (The Redball). The difference was in the mid-lane read. The Sting picks up earlier and has more continuation through the back portion of the lane. This difference is no due to the low RG Sigma Core.

Here is a video where I compare the Sigma Sting to several other MOTIV bowling balls on the 39 foot WTBA Seoul Pattern.

The Sigma Sting is a perfect compliment to the other recent MOTIV releases. Even though it has the same cover as the Cruel Intent, Tribal and Primal Rage, the shape of the hook is completely different. This is just what you want – bowling balls that go through the pins in different ways to optimize your carry percentage.

For me the best time to use the Sigma Sting is when I’m looking to blend out the pattern a bit. When the back-ends are a bit unpredictable, the Sting gives me my best look. The tougher the pattern, the more play my Sigma Sting sees. I am able to control the pocket really well on fresh oil with this ball as it seems to stay in the pocket zone longer than the other balls in my arsenal. When I need to make a big jump inside and open up my angles, I’ll switch to my Tribal or Rage.

SO …Replace my Sigma Tour will you?  I’ve always said all I need in my bag is a Sigma Tour, a
Sigma Tour and  a Sigma Tour as this ball has been everything to me! Its earned me multiple top 16 PBA Regional Finishes. A PBA 299 game and multiple league honor scores including an 842 Series. So you cant get it out of my hands. I won’t do it! When I heard we were coming out with a new Sigma I just couldn’t believe there was more that this line of ball could give. BOY was I wrong!  This ball not only gives me everything the original Sigma Tour did but so much more.  I’ve always loved the ball continuation the Motiv product line has provided but this one is just plain CRAZY!  With its repeatable, reliable and consistent motion and its unbelievable continuation through the pins the STING in now my new benchmark ball.  This balls shape combined with what the Cruel Intent and Primal Rage bring makes them the PERFECT 1-2-3 punch for any condition. This ball is truly amazing and will give you the response you are looking  for on THS as well as many of the tough Kegel Challenge  or PBA patterns.
This SIGMA STING is the ball you will grab to measure all other balls against. The proven Sigma core with the new  Pearlized shell is what makes this ball so versatile. Don’t miss out …COME GET STUNG!

The New Motiv Sigma Sting is a fantastic ball that will fit a huge range of styles and lane conditions. This ball will be a great, strong benchmark ball for the newer competitive bowler or fill a nice slot in an arsenal. The ball is angular but predictable and hits extremely hard. The Sting fits between my Rage and Tribal in hook and motion. The ball comes with a 4000 grit surface, and to me seems to be a good choice to match the core. We have not polished one yet because everyone has been so happy they are afraid to change anything. I am confident a polished surface would work great on the Sting if you wanted more length and angle. There have been other balls with this cover that we have polished and the motions were very good. The Sting hits very hard and if you have seen my ball motion video you will see an amazing move at the breakpoint that my lower rev rate is not used to. This is a ball that anyone who had the original Sigma Tour was looking for. I feel Motiv will keep this ball in the line for a long time but you don’t want to wait on getting one. The Sting is just too good.
The latest releases from Motiv have been incredible and I can’t wait to see what is coming next!

The Sigma Sting is a long awaited ball for anyone
that had the original Sigma Tour.
A great fit between the Rage and Tribal
Will cover a large range of styles and conditions.
A must have from Motiv.

The Motiv Sigma Sting is designed for medium patterns according to Motiv. The core is symmetrical (same core used in the Sigma Series), wrapped with the same cover, the Fusion Pearl Reactive used on the Primal Rage, Cruel Intent and the Tribal.  The ball is as advertised and more for me. It glides easily through the heads retaining energy for its down lane more.  The backend reaction is not nearly as angular as the Tribal but still delivers plenty of recovery and power when friction is encountered.  The Sigma Sting covers close to the same number of boards as the Thrash Frenzy, with a different shape.  I have already found that if the Frenzy is not carrying but hitting the pocket, the change of motion provides immediate carry benefits.
 Once the Sigma Sting finds friction the slowdown/change of direction is quick without being a checkmark.  The Sigma Sting then makes a strong move that is less sudden and sharp then the Primal Rage, but a quicker transition then the other balls in the Motive line without the Fusion cover. The Sigma Sting's make a continuous move at the end of the pattern and can cover a lot of boards in on the backend when the volume of the pattern is lighter or the length of the pattern shorter.  The core/cover combo has allowed me to play up the boards as well as playing very deep, but almost always the Motiv line has provided me this type of versatility. Getting the ball in the soup (house shot) in the middle of the lane will cause the ball to skate past the breakpoint, however getting it to the friction to early generally does not penalize the reaction as happens with stronger equipment The Sting also has been effective on wood with it not being overly strong, but strong enough to still give me plenty of reaction on the backends.  From the box condition of 1500 I had to add a little more shine, getting it to 2000.  As usual with this coverstock, changing the surface was easy and the results were immediate.
If you use this ball as designed it will be a very effective ball. To throw it on a burnt condition will require a healthy polish and a longer drill pattern but those will ball speed will be easily able to adjust with this ball.   I bowl with a number of athletes who are throwing Cruels or another ball in the Sigma line.  I believe this ball will be a great fit for their tournament arsenal.  Also, the Sigma Sting Motiv has a piece of equipment that acts as a great arsenal builder working in conjunction with the Cruel Intent, Primal Rage and the Tribal.  The coverstock has become very popular with its strong read of the friction and for those that like to keep their arsenal of equipment very linear these will be a great this completes (?) a very competitive grouping.
I'm very colorblind but really see this ball well with the color combinations Motiv used.  The Neomark Graphic makes the ball very pleasing to the eye, give it good shelf appeal and make it very easy to see the transitions of the ball on the way down the lanes.

Ok, this is what I was looking for to compliment my Primal Rage.  I drilled it exactly the same as my Rage and kept the surfaces the same as well.  I got exactly what I thought I would get.  An earlier, more continuous version of my Rage.  The super clean cover is wrapped around a super LOW RG core.  This means all the energy is saved for end of the oil pattern.  It just hooks so hard off the spot.  Unlike the Rage, you do not have to worry about throwing it through the breakpoint.  The Sting begs to be thrown hard!  I have still not changed the cover and found it to be the best benchmark ball I have ever thrown.  From 32' flood to a house shot that hasn't been oiled for days, you can find a way to use the Sing with a little versatility in your own ability. In contrast to the Rage, the Sting didn't kick the corner pins out as well but I didn't really need the help because it usually was a "10 in the pit" type of strike when it hit pocket.  However, I would much rather use the Primal Rage when the lanes were wide open.  The Sting was a bit too strong when the oil wasn't as fresh.  You can use it but it meant moving way left and not giving up the pocket.  That is generally not as fun as throwing the Redball at the ditch and watching the pins fly everywhere.

The Sting is the ball you want first out of your bag!  I recommend a Low RG drilling to go along with the Low RG core.  Using a "pin down" layout will take full advantage of all the power the Sting has to offer.  This is a must have for Motiv fans but should be a top contender if you are looking to add your first MOTIVated ball into your arsenal.

Description: The Sigma Sting is designed to combat medium oil conditions providing great length down lane with a continuous angular backend reaction. Utilizing the proven Sigma core the Sting is a versatile benchmark piece that will provide the perfect match up for both league and tournament bowlers on a variety of conditions. The cover of this gem is Fusion Pearl Reactive coverstock, the same cover that is on the Rage, Cruel Intent, and Tribal.

Reaction: My Sigma Sting gets through the heads without issue while retaining energy down lane, The reaction is not as angular as my Tribal as it rolls sooner and heavier but still has a lot of recovery and power when its encounters the friction. As the Sigma Sting encounters friction the response reaction is strong and continuous, the Sigma Sting can cover a lot of boards when the oil pattern is lighter or the length of the pattern shorter.


THS (41 feet): I played where the friction was which was down five and throughout league play I gradually moved further right  throughout the night no further than 15, The recovery and response to friction was phenomenal and I saw no burn up out of the Sting ever.  If I got the Sting into the oil the ball would skate beyond the break point and not recover, as the lanes break down and transition the Sting truly shines as it does not over reaction in the friction.

Wolf Pattern (32 feet): The Sting shined bright on this pattern, with all of the friction this pattern had to offer the sting covered as many boards as the red ball just with a smoother reaction. I stood ten from the left and targeted five to the right and watched the sting roll and recover, it was a smooth reaction all the way to the pin deck. If I accidentally got the Sting into the friction early I didn't pay a price for it as you would expect from other pieces, this ball excels in the friction.

Summary: The Sigma Sting is a great addition to the Motiv line up as it definitely fits in between the Rage and the Tribal, when you come across the over under conditions this is a perfect ball to have in your bag. I've also played with the surface taking it from 1500 polish, to 2000 without polish, to 800 without polish. Out of box the Sting allowed me to play right and stand in the friction without any hint of burn up , at this surface I was not able to play in the oil as the ball would skate through the break point. At 2000 the ball reaction was more delayed than it was at 1500 polished and still did not react as well as I expected to in the oil, it was a delayed smooth reaction. At 800 without polish the Sting became more suitable to play in the oil with, at this surface I was able to play more normal shot while standing in the oil. The Sting responds very well to surface adjustments and when used on its intended condition(s) its flat out phenomenal , the Sting is a brilliant arsenal addition along with the other recent Motiv gems. 

Sting without warning and with no apologies.

The Sigma Sting is the latest release from Motiv Bowling. The new Sigma Sting brings together one of the best cores and coverstock that Motiv has ever produced and what turned out was a benchmark ball that everyone will love. The Sigma Sting provides great length and a smooth angular backend motion that continues through the pins and does not stop. The Sigma Sting is built by the award winning Sigma core and the Pearl Fusion Coverstock and what you get is a striking machine. What these to do is make the Sigma Sting a perfect ball for any league bowlers because of the angular backend motion that’s not too jumpy and has the most continuation out of any ball Motiv has ever made.

INNER CORE -     Sigma
COVERSTOCK -   Fusion Pearl Reactive
FINISH1 -           500 Grit / Power Gel Polish


Most of my friends know that the Sigma Tour is what got me to really look at Motiv. It was arguably the best ball I have ever thrown until I got the Sigma Sting in my hand. The Sigma Core if one of my all time favorite cores because it retains its energy so much while in motion down the lane that the stored energy will just complete destroy the pins once it hits its breakpoint. I love every time I throw the Sigma Sting because it is exactly what it’s labeled to do, be a great benchmark ball for bowlers and a true house shot killer. I can’t say enough how good this ball is other than you have to get one and see for yourself. The Sigma Sting is and will be your go to bowl when you get in trouble on any shot.

Likes – Everything about this ball

Dislikes – None

I recommend this ball for all types of bowlers; you won’t be disappointed on the performance of this ball.

My Motiv Sigma Sting: Drilled with the pin above my bridge and the CG kicked out with a hole in the P2

The Sting has the Fusion Pearl Reactive that can be found on the Primal Rage, Cruel Intent & Tribal. The core in the Sting is the “Sigma” core which is found in the Sigma line of bowling balls.

The cover comes out of the box at 1500 grit sanded with polish.

Conditions I have used the Sting on: Yellow Brick Rd, Bourbon Street and various house/modified house shots.

Where it fits in my bag: It's my new benchmark ball and a great ball for the local THS.

When I use it: This is a ball that all level of players can use during their nightly league sessions. Tournament players will see this ball in their hand around game 3 if on a longer pattern.

The Ball: MOTIV Sigma Sting

The Style: Power Stroker. 16.5-17 Speed. (Rev rate untested since shoulder injury.)

The Conditions: Riverside Lanes in Laughlin, Nevada. 40 FT House and 39 FT Modified Tournament Pattern. High friction environment.

The Plus: A fantastic benchmark ball that provides enough early read with a strong and smooth continuation that is replacing my Thrash Frenzy as my Benchmark in my arsenal.

The Minus: None really.

The Score: 5 out of 5.

After taking the first half of winter off to rest back up and reevaluate where I was going to be bowling in the new year, I decided to start punching up my equipment and throwing what appealed to me the most. Out of everything in the Motiv line I had to admit that this was not the ball I would of thought of as the new Benchmark in my bag simply because I had not been a huge fan of the Sigma series on my house condition which tends to be drier and break down faster. This ball has changed that conception and replaced my Thrash Frenzy as my current favorite ball on the lanes.

With the earlier Sigma core balls I found a lot of over/under reactions especially on the fresh in my home house. Combing the #REDBALL coverstock with the Sigma core has eliminated this problem by giving me an excellent read down lane without the concern of flat corners or an unreliable breakpoint. Even as the pattern broke down and became spotty at best, the Sting continued to read the blend well and I found myself making simple one and two board adjustments as opposed to drastic moves as I had to with the earlier balls.

In the end I consider this to be a house shot killer and a must have for a variety of styles and drill layouts. I have yet to see anyone throw this who absolutely dreaded the ball and take that as a sign of great things to come. Get MOTIVATED.

The pearl Sigma Sting™ is tuned for medium oil, making it an incredible benchmark ball.  It provides great length and a smooth, but angular backend motion that continues confidently through the pin deck.  This is the first time MOTIV has put a pearl cover stock around the Sigma™ core. 
The Sigma™ Sting from MOTIV™ is an incredibly versatile benchmark weapon that will be used by a wide array of bowlers.  It is a must-have piece for bowlers building a solid tournament arsenal.  It also provides the perfect shape for many league bowlers that need something angular, but not too jumpy on a house shot.
I punched up my Sigma Sting with my favorite layout (55 X 4 1/2 X 40) which is with the pin just slightly over my bridge. I have been trying something different here lately and it seems to be working out.  I have been putting my favorite layout in every new ball produced by Motiv.  I normally play around with different layouts versus using my favorite layout all the time. By doing this I am able to let the core and cover be the difference in ball reaction.  Its more helpful because I am truly learning my arsenal and Motiv's product line better than ever before.  The Sigma Sting has not dissapointed at all, thats for sure. I love how the Sting can be the first ball out of my bag and tell me exactly where I need to be. Whether its moving a few boards left or right, or perhaps moving up to a Motiv Cruel Intent or down to Motiv Tribal. This decision is made considering variables such as lane condition, lane surface, and etc. The Sigma Sting is very clean through the front part of the lane with a strong read in the midlane with a smooth but angular reaction in the backend.  It is not as angular as the Tribal for me but its definitely more predictable, which is great when your encountering too much over under on the lanes.  Compared to our very popular Sigma Tour, the Sigma Sting gets much more length and has a quicker response to friction (more angular).  The Sigma Tour is much smoother overall than the Sting.  But the Sting does make a great compliment to the Tour if the tour begins hooking to early.  The Sigma Sting has earned the right of becoming my "benchmark" ball.  Which is great because thats exactly what Motiv advertises it to be. They hit it right on the head!  Don't waste anymore time and order yours today! Its time to Strike Up a Buzz and Get MOTIVated!!!!

Title: Sigma Sting = Versatility!
Post by: Wya_Rya on February 10, 2014, 06:26:58 PM
So the question that must be plaguing all you MOTIV faithfuls or those looking to break into the brand but are not quite sure where to start, what does MOTIV have in store for you? Well that is a very simple and exciting answer. I have two words for you, the Sigma Sting! This ball has no limits to how it can be used on the lanes. The Sigma Sting has re-defined the word versatility for MOTIV. Once again, championing the cover stock that made their presence known within the bowling Industry, the Fusion Pearl Reactive has finally been wrapped around the Sigma Core. This brings a new aspect to the Sigma line with a pearl but yet powerful cover stock that provides great length but still manages to provide both smooth but yet snappy back-ends.
There is no denying that this ball will surprise both the individual who picks up this piece and begin rolling it down the lane as well as those watching. The Sigma Sting has become by far the best ball in my bag and it is rare that the Sting isn’t one of the first balls out of my bag. I bowl in both first and second shift leagues and if this ball was the only ball I remembered for either league, I would be set. With the amount of energy that is retained for backend motion, I easily open up the lane as I move in as the 2nd shift shot continually breaks down more and more. Turning to the other side of the coin, I can just as easily tighten up and go more down and in on a fresh shot. When anyone claims versatility, its hitting power comes into question as the angles change with any ball, the Sting must have missed that memo. The first game out of the box, playing 2 different angles, left lane was very snappy, any shot left of the 12 board on the left side of the lane by mid-lane was going to make a nose dive for the head pin. The right lane was almost a polar opposite as I needed to play more up and in. This ball, out-of-the box, I threw a 279, only leave being a swooshing 10 with pins flying left and right but no such luck to take the pin out. Following that opener, within a month, I had thrown a 279, 290, 300, and a 280 (not all in one set of course).  If you’re looking to fill your bag with that essential go-to ball, especially for a tournament bag, the Sigma Sting will create some envy among the rest of your equipment as you may not want to pick up another ball from the bag again. Go out there and strike up a buzz!

If you are looking for a strong skid flip piece, this is a ball you should highly consider.  I have my Sigma Sting drilled with the pin over the middle finger which puts it about 5" from my PAP.  This layout on this ball gives me good length with a strong motion at the back of the pattern.  I would not recommend using this ball with this particular layout on a fresh condition unless you are trying to open up the lanes from the get go.  This ball would be a great compliment to the Covert Revolt which is a strong arcing motion.  I would recommend starting with a Revolt on fresh heavier patterns then switching to the Sigma Sting when you move left and need something with more angle at the end of the pattern.

Length:  40 ft AMF HPL (house #1), 43ft AMF HPL (house #2)

Volume:  Medium

Type (THS, Sport Pattern etc):  THS


Likes:  Clean cover, strong predictable backend motion, versatility, carry power

Dislikes:  None

Having thrown Storm and Roto Grip almost exclusively for the past few years, the Sigma Sting really got me interested in checking out Motiv.  After finally picking one up, all I can say is damn, why did I wait so long?

Knowing that the Sigma Sting is tuned for medium oil, I figured put my favorite 4x4x2 layout on it, which is what I use with my Storm Hy-Road.  The big reason is I wanted to compare how this would be with that specific ball.  Plus, I wanted a good combo of length and backend motion.

The first place I threw this ball was at the house where I bowled my junior leagues in a long time ago.  That place typically uses a 40 ft THS on older HPL lanes.  Also, the pattern is known to give some over/under in some cases.  The Sigma Sting made the pattern look easy.  I could play straight up the boards or swing it from inside, and it was really surprising how much miss room I had.  Playing outside, the ball really shined by being very clean up front, providing a predictable midlane and then saving a ton of energy for a huge backend move.  Inside, the ball was still very clean, but provided a nice hard arc that didn't over react.

The other thing that is nice with the Sigma Sting when compared directly with my Hy-Road is that it was not nearly as speed sensitive.  I could still throw it harder and the ball had no problem recovering. 

Then, the second place I gave this ball a try is the house where I get my stuff drilled.  That place also uses AMF HPL, but has a longer 43 ft THS that has additional volume.  Just like the first place, I was able to play outside with no problems at all.  Moving inside and slowing my speed down, the Sigma Sting also worked very well and again prevented over reaction.

Versatility is a great thing with the Sigma Sting.  Regardless if I keep my hand behind the ball more to play straighter/throw harder around 20-22mph, it shines.  If I get my hand around it more with some more tilt/rotation and slowing my speed down to around 18-19mph, it also shines.  Regardless of what approach I took, the ball flat out works.

Last but not least, carry is excellent with the Sigma Sting.  The continuous motion the ball has when it hits the pins helps keep pins low, and has no problems with sending messengers for more strikes on the board.

Motiv has a huge winner here with the Sigma Sting.  The others who mentioned this is a perfect benchmark ball are speaking the truth.  As much as I enjoy what my Storm Hy-Road can do, Motiv takes the weaknesses I mentioned in my prior review of the Hy-Road (speed sensitivity) and gets rid of it.  In my case, it will replace my Hy-Road as my benchmark piece as it has so much versatility.

I can say that Motiv has absolutely impressed me with this ball.  If you have never thrown Motiv before, what are you waiting for?
