Description

The Roto Grip Sinister is just mean. The pins and your opponents are going to feel the wrath.

The all-new Cage Core is designed to produce superior midlane all while providing backend continuation. Pair that with the super-strong 76H Hybrid Reactive Coverstock finished at 4000 Grit and you’ve got the perfect ball for long and heavy oil patterns.
