Hybrid Cover Bowling Balls Doesn’t Mean What You Think It Means | Coverstock Designators Part 3 of 3

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.

The MicroTrax (Micro Nanoparticle Traction) Coverstock offers the optimum balance of midlane traction and responsiveness to friction thanks the blend of nanoparticles throughout the coverstock. This formulation maintains its surface profile texture longer to ensure you get maximum performance while displacing oil at an above average rate compared to other coverstock materials on the market today.

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.

BEHIND THE DESIGN…
Dating back to the mid-1950’s, there is a reason Roto Grip is often referred to as the “Original High-Performance Bowling Ball Specialists.”

Our latest asymmetrical creation continues that tradition with the development of the RST Core which produces consistent core torque and energy transfer down lane where it is needed most.

From there we formulated the most versatile MicroTrax Hybrid Coverstock to date which produces optimum responsiveness to both oil and friction.

It’s ok, you can thank us later!

RST – Roto Star Tour Core…
Professional bowlers like to see continuous motion down lane with minimal deflection as the ball enters the pocket due to their rev rates usually being on the higher side. This logic was the basis of development by the R&D team as they looked to create a core that would maintain dynamics after drilling in order to maintain a higher level of core torque down lane. The larger mass at the base of the core does indeed create that. Especially since when drilled, the thumbhole will always end up near the bottom of the void area not to affect the bottom mass of the core all that much. Thus, making this core a “Tour Level” type core design.

Behind the X-1 name…
When it all began back in the early 1950’s, Roto Star (later known as Roto Grip) quickly became known as the “High Performance Bowling Ball Specialists.”

Because of this industry leading mantra, and with the latest creation of the Roto Star Tour Core, it only made sense to go back in time to recapture the vibe and pay homage to those balls that set the standard for technology and development.

That is how the RST X-1 was born!
