Motiv Cruel Bowling Ball Core
The Cruel™ core is the first asymmetric design from MOTIV and it is crazy aggressive. The specs are completely maxed out. The 15# C51 has a 2.48 RG, a .060 primary diff, and a .030 mass bias differential. (That’s insane!)
The Reverb™ outer core is a low-density polyester resin with pin piercing hardness and strength. Rather than absorb impact energy, this outer core reverberates energy as it explodes through the pins.
