I had my ball drilled with the pin down above the fingers. This provided me with a strong midlane roll and a very effective continuous, backend! This ball gives provides the hooking power and reaction I need on the longer oil patterns.

The new Cage core along with the 76H hybrid coverstock gives me the look and the down lane reaction I am looking for. With this cover I don’t have to worry about the lanes getting burned up. This ball gets through the head and maintains its power all night long. What a great addition to the HP4 line and my arsenal.

The Sinister is my first ball out of my bag on sport shot or tournament condition.
