The Roto Grip Unhinged is the latest release from Roto Grip in the HP3 line. This ball uses the same Late Roll 69 core as the Hysteria. This time, this weight block is surrounded by the 60M pearl cover that comes out of the box at a 1500 grit polished finish. This change in coverstock allows the Unhinged to have more length, back end, and total hook than the Hysteria.

We saw this ball have its best reaction on our medium test pattern. The Unhinged easily cleared the front of the lane, started to pick up strong in the midlane, and then made a powerful move at the back end ...
