The Deranged is the follow up to the Disturbed in the HP3 line for Roto Grip. The Deranged uses a pearlized 61MH coverstock to surround the same core as used in the Disturbed.

The Deranged gave us a big skid/flip motion as it made its way down the lane, with our best reaction on the medium test pattern. Cranker loved that he could really open up his angles on this pattern with the Deranged. He was easily circling the ball around the part of the lane where Stroker and Tweener were lined up. Stroker and Tweener liked the big reaction
