About this ball

THE PROOF IS IN THE ROLL!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.
