Track
The Track Proof Hybrid is a hybrid reactive bowling ball with the Proof core. RG 2.519 and differential 0.052 at 15 lb. For medium oil – heavy oil. No longer made.
The Proof Solid and Proof Pearl have been excellent performing balls on the lanes for Track fans this last year; the response to these two have been great from every type of bowler. The Proof Hybrid combines the best elements of these two successful balls into one great ball. The Proof Hybrid might be the only ball that will get Track fans to put their original Proof balls down.
