The Proof is a new high-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.

The Track Proof is an amazing Medium RG, Higher Differential Piece that has become a must carry in my bag at all times as it has more than proven itself to be a versatile piece that just matches up on House, Challenge and Sport Conditions. It's ability to read the mid lane while maintaining the necessary energy to get through the pins correctly on multiple surfaces and lane conditions has resulted in my getting a 2nd one to stash for a rainy day.
