Cruel C51 LE

The Cruel LE contains the crazy-strong Cruel asymmetric core and a new additive to increase the surface texture (Higher Ra Value) of the Black and Red Formula-5 Pearl Reactive coverstock. This feature helps low to moderate rev bowlers cross more boards down the lane in medium to heavy oil. High rev bowlers will find that this additive provides a smooth, but very strong backend motion. It's not your typical pearl. It's a Cruel World! CONDITION: Medium to Heavy Oil INNER CORE: Cruel Asymmetric COVERSTOCK: Formula-5 Pearl Reactive BOX FINISH: 2000 Sanded / Power GelĀ® Polish 15# SPECS: RG 2.48, Diff .060, MB .030 DRILLING RECOMMENDATION: Because the Cruel core is so strong, we recommend keeping the mass bias (MB) mark at least 4 inches away from the bowlers positive axis point (PAP). Also, for high rev bowlers, a shorter PIN to PAP distance can help tame the track flare. A 3-inch PIN to PAP distance has worked very well for some high rev bowlers.
