Description
The Proof is a new upper mid performance release with possibly the strongest core numbers ever in this category and an updated Prime cover that will get Track Bowling fans excited. The Proof is very strong and continuous and surprised our testers because it is usable for a long time and does not seem to want to quit, despite the strong core, cover, and finish combination.

This proof is a lot of ball for your buck. My pin down layout really smooths out the entire reaction. I get a great midlane roll and plenty of backend reaction to make anyone happy. Straight out of the box and a great reaction with no surface changes needed. It was instantly a favorite of mine because of the motion this ball shows on the lanes.

versatile ball
This ball is definitely a main stay in the bag. I can use it on various of patterns that have volume up front. Even when there is some carry down i can still get left and open the lane up and the ball doesn't quit..only time I can see this ball having issues is if the fronts get burnt up..other than that this ball is pretty versatile.
