Introducing the Rule GP2, the newest high-performance innovation from the Track team. The Rule GP2 defies logic. Never has the industry seen a particle ball that is aggressive in the midlane without giving up angular, continuous backend motion in heavier oil environments. The Rule GP2 freatures a combination of two different particles precision-injected into the aggressive Goo reactive. Track then matched the new coverstock with the large-volume Morpheus 1.0 core; added the high-volume Rev-Lever attachment from the Rule and the Xception core for strong mass bias; raised the RG for more energy retention; and attached a flip block for awesome backend reaction. Aggressive in the front and the backend, the Rule GP2 delivers the technology that has made Track the industry leader in core/coverstock innovation.

15lb, 14.5-15.5 MPH, medium revs, AMF synthetic lanes, medium oil with HUGE carry down! Not too sure about the drilling of this ball.

I love this ball!!! I used this ball last Friday and it was awsome! The house had a long oil pattern (I found out the lane oiler was not stripping the backends becasue it was broke). So, I had lots of oil to try this ball in. This ball chews through some oil!!! The hit and carry are outstanding!!!!! If its anywhere in the pocket, you might as well put an X on the scoreboard!!!!

Thank you Track!!!!!!!

I am a 16 year old player and bought this ball for early hook. That's what it did.
I am med rev player and shot 685 out of the box, It's a great ball but you have to know when to put it in the bag for when the lanes dry up.

Ball specs: 15 lb 2 oz, 2" pin, 2 oz of top weight.

I needed a heavy oil/tournament ball for my arsenal so I picked up this one. Ball was drilled pin under ring, mb on VAL. Covrstock left in OOB. I have thrown it on a few different lane patterns to see what this ball will and wont work on.

First shot, THS, medium oil tapered out to 8. Dry outside of that.  Oiled to 28' buffed to 40'. Fresh backends. The ball is not designed for this type of lane condition. I needed to move way in and play a small belly shot to stay in the oil. I was lined up standing on 30 pushing the ball over 15 at the arrows with my break point at 12. I was able to get to the pocket and strike pretty consistently. Ball had good length and then popped on the backend.

Second shot, same shot as above only second shift. Couldnt use this ball at all obviously. The heads were shot and plenty of carrydown. Ball burned up in the first 20 feet and would do anything. Ball is not make for this shot.

Third shot, tournament shot, flat heavy pattern out to 5, tapered to the gutter. Pattern was long as well, not sure on the exact distance but if I had to guess, I would say it was probably 42 to 45 feet in length. The GP2 shined on this shot. It is really an oil monster. It basically ignored the oil and gave me a nice reaction. I was able to stand on 23 and play over 13 at the arrows hitting 10 at my breakpoint. The ball got down the lane and had a hard move on the backend. It hit the pins with tremendous power. I had very good carry with the ball.

Overall, the ball works like a gem on what it was designed for. Heavy oil. I have never seen a ball with that much recovery on heavy oil. This one is a winner even with its limited usage. It retains energy very well and unleashes it when it hits the pocket.

If you need a heavy oiler for your arsenal, dont hesitate on this one. Another winner from Track!!

Needed a ball that could move very strong in oil. Todd Adams drilled this ball just to do that. I'm a very speed dominant player with a medium rev rate that uses the outside line alot to make a move for the pocket. This ball allows me to play much deeper on those fresh house shots as I expected. The pin is drilled just right and below my ring finger with CG just alittle right of the pin. This ball Revs up early for me and makes a strong arc into the pocket. Carrying for this ball is not an issue. Just know when to put it away. When lanes start to break down this ball will leave 10 pins. Great ball by Track. I give it an 8 out of 10.
--------------------
Damn not another 10 pin

I just recently started to use this ball again after about an 8 month hiatas without it. So much stronger than my Alter Ego. Can only use it for a short period of time as it starts to hook very early after about 1.5 games. Then I switch to alter ego by columbia. Shot a couple of 299's and one 300 in practice over Dublin.

"NEVER settle for less."

I have used this on a Sport Shot and heavy oil house shot on synthetics and wood. It allows me to play a deeper angle on the sport shot that no other ball in my arsenal will let me play. It is great when the house shot is flooded but I have to be careful and watch the carry because it starts to burn up and hit more softly eventually after a game or two and you have to know when to put it away and pull out the polished ball. It is a good ball to have in the arsenal, especially for a low rev player with speed like me. I still suck on the sport shot but it is not the ball's fault  that I can't repeat shots, without it I would probably do even worse.

This is the first track ball I have ever bought, and I must say that whatever Track is doing, I hope that it keeps doing it.  This ball is great for oily lanes, in fact I wouldn't throw anything else, except for maybe the Tour Inferno.  I have had only one honor score with this ball (299, it lacks some carry *cough 10-pin cough*) but I have had mulitple 290 and 279 games with it.  I think the only problem with this ball is that it doesn't transition really well from oily to dry lanes, I think one is better off switching when he or she notices the ball really starting to snap up.  Other than that though, I really believe that this ball can carry a bowler through some of the slickest conditions out there.
