Our obsession with helping players of all ages and styles conquer various lane conditions while abiding to forthcoming governing rules, led to the development and creation of the asymmetrical E.T.™ Core (Equalizer Technology Core) which features built in cavities in order to increase weight displacement after drilling without a balance hole to increase overall ball motion.

eTrax Hybrid Coverstock
Type
Hybrid Reactive

Our purest form of reactive material to date, the Enhanced Traction (eTrax) coverstock sets the standard as the material to which all other materials are compared and tested. Formulated to provide the “true reactive” response on a variety of conditions by easily clearing the front of the lane while aggressively responding to friction down lane, the eTrax material flexes its resilience and durability day in and day out.

Equalizer Technology (E.T.) Core
Roto Grip E.T. 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.
