Roto Grip Rumble Bowling Ball

Guts: The brand spanking new Late Roll 51™ core was designed to create the same amount of length as the previously used Neutron™ core in this line. However, this new shape yields a little less differential which means more control at the breakpoint. 

Grit: The newly formulated 55M™ solid reactive coverstock was created to combat medium oil conditions. This coverstock will easily clear the front part of the lane yet still provide the needed traction to be competitive on those in-between conditions. 

GRIME: The combination of the brand new Late Roll 51™ core and the brand new 55M™ solid reactive coverstock will give you a ball that bridges the gap between the Wrecker™ & Shatter™ reactions and the Scream™ & Shout™ reactions.
