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.

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.
I can’t say enough about this ball. It is a quite strong, asymmetric solid that gives me great traction as well as strong down lane motion. This is the first solid I’ve had that doesn’t burn up on house conditions. Usually I require a good amount of oil to throw a solid like this or most of them tend to burn up some and disappoint on the back half of the lane. Not this Proof though, it still has good energy on the back half and goes through the pins well. So, I get the predictability and heavy roll of a solid with good backend still without the over/under that sometimes comes with a pearl or polished ball for me. This is drilled 45 x 3.75 x 25 and I am about 16.5 mph (at the pins) and 425 or so rev rate.
