Roto Grip Clone™

CLONE - "a thing that duplicates, imitates, or closely resembles another in appearance, function, performance or style." And well, since the last version of this core part was unwillingly abducted, we felt it was our responsibility to the entire bowling galaxy to "clone" it and mix in a few upgrades & performance enhancing tweaks that bowlers of all skill levels on planet earth will benefit from. And just as before, the reasons that led to the creation of the original E.T. Core that featured out of this world core technology better known as “equalizer cavities” to emulate the use of a balance hole, the CLONED E.T. Core also does that, but MORE. Yes, you read that correctly, the same benefits as before, only MORE motion overall. Simply put, this version is the next generation all bowlers need in the bag.

OptiTrax™ Solid

Based on years of testing and research, we found this direction of coverstock chemistry provides a more balanced oil displacement/absorption throughout the entire lane thus creating more consistency/predictability shot after shot in terms of skid distance, midlane traction, and response to friction down lane. Derived from the advancements of both the eTrax™ and eTrax™ PLUS solid materials the last couple years, we found this new direction of solid material that complements both of those without overlapping them. Because variety is the spice of life, especially here on planet earth.

Cloned E.T.™ Core

In our pursuit of creating out of this world ball motion, we felt it would be beneficial to all bowlers on earth to re-imagine the proven E.T.™ Core (Equalizer Technology Core) in order to best complement all of our other asymmetrical cores. By simply changing the density of this single piece part, it not only lowered the RG values of the 16lbs – 14lbs options, it also, increased the Differential values in those parts as well, thus increasing the overall motion potential. So, what does all of that actually mean? It means more overall midlane and downlane motion than the previous version of this core thanks to the increase overall dynamics and the benefit of the built in “equalizer cavities.” And just as before, the more effort focused on core placement before drilling, the easier it is to dial in the desired ball motion.
