Roto Grip E.T. Bowling Ball Core Info
Roto Grip Equalizer Technology (E.T.) Bowling Ball Core
E.T.™ Core = Equalizer Technology™ Core... This space aged creation was developed with built in cavities to emulate the use of an extra hole since as of August 2020 the USBC deems them illegal. The built in "Equalizer Cavities" will help increase midlane motion and continuation down lane.
