Sanded Hybrid Reactive Bowling Ball

My winning personalities are dying to break out.

When I told them I was all things to all people, they locked me away. Now I’m ready to bust free and destroy those who doubted me. Soon they’ll get a taste of my desire to win at any cost. And once they see my scores, we’ll find out who really needs the rubber room.

While they’re busy trying to find their way out of the front, I’m already halfway down the lane. My symmetrical Middle Roll 70™ core makes me move in the midlane and backend like nobody’s business. In fact, it’s almost unfair.


They thought I’d never get out. My deception worked as planned. The pearlized portions of my 63MH™ Hybrid Reactive Coverstock give me more length through the front of the lane and the solid portions give me predictable, controlled motion down lane. Here I come!



Together with the Disturbed™ and Deranged™, I’m ready to continue the reign of infamy that the HP3™ lineup has inflicted upon the lanes. On Medium/Heavy oil conditions, I’ll give you more length than the Disturbed, but with less backend snap than the Deranged. Nothing can hold me back.
