I Drilled by Rule GP2 with a 41/4 x 2.5 in pin. I drilled my balance hole 3 inches below my PAP. This ball flat out moves and never seems to lose energy. I can't wait to see what it does on a long regional pattern. For a ball that is so strong even with a little surface it clears the front very nicely and rolls VERY strong through the midlane. I have yet to find a condition where there is too much oil for this ball. Also this ball does not seem to burn up like most strong particle balls. AMAZING BALL.

This has to be my all time favorite heavy load particle ball.

Since drilling it I have made the finals in a PBA east regional shooting
300 in the process. Won 2 local tournaments 1 where the finals were bowled on TV.

This ball is actually the 2nd GP2 I drilled ( 1st was 16 lbs I switched to 15 lbs)

I put the pin 4 inches next to ring finger 4 inches from PAP CG 5 inches from PAP x hole 2 inches below PAP MB strong.

This ball clears the front with ease, rolls in the midlane then backends hard.
This ball seems to carry every type of hit from light to kick 4.

I have left mine box finish so it does need oil in the front.

If you are looking for a ball for heavy to med oil that doesn't hook early
the GP2 is the one.

This ball is another winner from Track!!!!!!!

Son look...my abcs say ooooooooo.....dad...those are cheerios

I bowl in a wood house cooked heads. 38 ft pattern buffed to 42 ft wood lanes. Ball speed 18-19 mph, med revs. Drilled my Gp2 with pin above ring finger. Pin 2 ¼ above grip line. With a 3” kick of mb to the right of my thumb. Weight hole is 5’ over on my grip line. Great for heavy oil. And very good with carry down. The Gp2 Rule and Aressenal Aggressive and Exception make a great 1,2,3 punch in the bag. Rember bowlers when done bowling clean your equipmewnt with Track clean and dull.

For the GP2, I used my favorite strong particle cover layout, a 5" pin about the ring finger w/ a 4 1/2 Mass Bias distance from my pos. axis. A 25/32" balance hole drilled 2" deep on axis took the static balance to 1/2 pos.

The box finish handled a high volume house condition beautifully, as the core revved up in the 30' range and even given the layout, I got 5" of track flare, 3" of it in the oil pattern. Smoothing out the surface with Clean N Sheen to 1000 allowed me to square up to the oil line at second arrow and feed it to the dry with a powerful backend move to the pocket. The multi-particle coverstock ended up being more versatile that I thought it would be. On a 40'
22ml volume sport pattern, a surface change back to 500 was necessary to let the ball read the mid-lane well enough to get a consistent backend reaction. Overall, all the hook just about any bowler will ever need on all but the most dry conditions, and layout is of greater effect than in reactive coverstocks with symmetrical cores.  Chuck Schommer, Track Amateur Staff

The Rule GP2 hooks and then some! WoW! This is arguably the most hooking ball on the market today! I have never been able to play ultra deep angles until I had this one drilled up for me. I really did not have much of a choice because the ball is really aggressive! On a THS, this ball played deep inside gave me a nice arching back end with a lot of bang and crushed every pin in its path! This is an excellent piece of equipment for heavy oil, sport shots, and moderate heads with plenty of carry down. If you do not have one, I highly recommend it! This ball hits really hard and does not leave 10's all that much! Wonderful job Track! You guys really went overboard with this one!!!

15 lb., 2 oz. top weight, 2" pin.  Drilled with pin above fingers, slightly to the right of the bridge.  5 1/4" pin to pap, 3 5/8" pap to mass bias.  Mass Bias located approximately 1" down and to the right of the thumb.  Laid out for lighter oil, lower revs, medium length, medium flare, hook & set reaction, and strong backend.

All I can say is WOW!  I have put about 10 games on the ball so far, and I would venture to say that I only really had enough oil to play this ball in 2 of those games.  I knew that I would not be throwing this ball a lot in my hometown house because the oil is on the lighter side.  The first day I got the ball, last week, I threw eight games and spent the entire time moving left searching for a way to keep this ball on the lane.  I am a tweener, and I have never been able to play over by the left gutter, but with this ball I get to pretend to be a cranker.  So, this has been a real learning experience for me.  I had a good idea of how the ball played after that, so I gave it another go last night and threw a 240 first game...Ball was very forgiving, held line well, came back when too wide...gave me about a 5 board hold area...nice.  Ball was carrying great when it wasn't burning up...keeps pins rolling around on the deck and tripping out leftovers on bad balls.  By the second game I had already blown a hole in the pattern and had to put the ball away.  

This ball is easily the strongest ball I have ever thrown.  It had my partner with his Ultimate Inferno very jealous.  This ball revs up slow, then gets faster in the midlane where it starts to make a big arc.  Then about halfway through the arc it hits the backend and flips left HARD.  One of the more impressive reactions I have seen.  The ball is about 10 boards stronger than my Big Time, and IS NOT your typical big arcing particle.  Can't wait to get a chance to play on conditions that match up better with this ball.  I will update this post and let everyone know how the ball works out after I throw it some more.

This ball rules.  I threw it last night in a league and managed to run up 11 in a row.  Should have been a 300 except for it left a pocket 7-10 in the first frame.  I am in love with this ball.  While everything else in my aresnal dies when it reaches the pockets, this ball hit like a freaking freight train with lots of pin action.
