Consider Yourself Warned

Roto Grip UFO™ Alert - Assembled for every bowler in the universe, the UFO™ Alert is here to help you navigate those Medium to Medium/Heavy Oil Conditions with ease. No matter your style, no matter your rev rate, no matter your speed, the E.T.™ Core (Equalizer Technology Core) with its built in cavities, is sure to create great overall core motion every time due to the added mass displacement when drilled. And we can’t forget about the eTrax™ Hybrid Coverstock which is made of 2 parts pearl and1 part solid. This cover combination aids in creating plenty of responsiveness to friction down lane without being too angular. Thus, making this combination of core and cover one of the most ideal options ever created for most any house type oil condition on planet earth.

eTrax™ Hybrid - 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.

E.T.™ Asymmetrical - E.T.™ Core = Equalizer Technology Core. This space aged creation was developed with built in cavities at the base of the inner block to emulate the use on an extra hole depending on how you drill it since balance holes are no longer legal in sanctioned competition. The premise of the lower RG and high differential naturally translates to more flare potential, but, add in these “equalizer cavities” and you have yourself built in increased dynamics after drilling.
