50.5 Hook 13 Length 15 Breakpoint Shape Core Design: The new slice-of-bread type Caliber symmetric core can add 12% more energy transfer upon impact, says Roto Grip.

Roto Grip Riot

Mid-price does not always mean mid-performance. The Riot provides control and great pin carry on lighter to medium volumes of oil. The Riot will read the lane sooner and smoother than will the Dark Star due to the solid reactive cover.
