Thats right, after a brief hiatus, we felt there was no better time than now to resurrect and revitalize this gap in our product line. We saw the posts, we heard the cries, we read the messages, we heard the yells, we jotted down the in-person requests. You SPOKE; we LISTENED! From the start we knew that to make the HP2 Line great again, we had to re-imagine what the overall performance from this line of balls should react like. And trust us when we say that this was not an easy task. Multiple bowling styles and countless tests paved the way to our final decision to bring back and modify this legend to battle the conditions and beat up lane surfaces of today. Trust us, you won’t be disappointed! So, whether you need something a bit stronger than your favorite Hustle, or you need a good step-down ball from your more aggressive higher end stuff, this wrecking ball has you covered. From the PURE-Response Hybrid coverstock to the Wrecker AI Core on the inside, this ball checks all the boxes. Versatility CHECK!... Clean through the heads CHECK!... Reaction down lane CHECK!... Style & Appeal CHECK! Trust us when we say YOU NEED THIS IN YOUR BAG! RG: 16lbs(2.55) 15lbs(2.54) 14lbs(2.59) 13lbs(2.58) 12(2.64) Diff: 16lbs(.048) 15lbs(.045) 14lbs(.046) 13(.047) 12(.037)
