Roto Grip Hysteria vs the Disturbed and the Deranged.
Make your opponents lose their minds when you throw the Roto Grip Hysteria!
The Hysteria features the Late Roll 69 Core which provides great length with the box finish of 1500 Grit Polished on the 6tMH Solid Reactive Coverstock. This combination will give you a ball that clears the heads and has a devastating but controllable backend reaction. The Hysteria will cause the pins to have to be committed on medium-heavy oil!
