Heavyweight Showdown | Roto Grip Clone vs Storm DNA!

Roto Grip Clone Bowling Ball

We are dedicated to improving players’ ability to conquer various lane conditions and comply with governing rules. This led us to create the asymmetrical Cloned E.T.™ Core (Equalizer Technology Core). By featuring built-in cavities, this avant-garde technology can increase weight displacement after drilling, without the need for a balance hole, resulting in greater ball motion.

Engineered for medium-heavy to heavy oil conditions, this cloned E.T.™ Core is truly exceptional. The base of the inner block contains built-in cavities, mirroring the effects of an extra hole, depending on your chosen drill. Given balance holes are no longer legal in sanctioned competition, we’ve devised a solution for capturing more flare potential and dynamics.

Our innovative E.T.™ Core boasts a lower RG and high differential, the perfect recipe for increased flare potential. However, by integrating these “equalizer cavities”, we’ve unlocked even more built-in dynamics after drilling.

Experience unrivaled midlane traction and friction response with the new OptiTrax Solid Coverstock’s blend. Its prolonged texture ensures your ball maintains maximum performance by displacing oil faster than other coverstock materials on the market today.

Storm DNA Bowling Ball

You may have already seen how a bowling ball is made. We start from the innermost part, the weight block, and work our way out. In this case, it’s the inventive Supercoil weight block. The intent was to develop a super low RG shape with a greater undrilled intermediate differential. Traditionally, weight blocks with more of the mass placed around the equator drive the RG down and read the midlane better.

The cutaway on the Y-axis helps to maintain dynamic integrity after drilling. When it’s time, the coverstock is poured. In just a few minutes as the liquid transitions to a solid, an extreme amount of heat (about 200 °F) needs to be released for this to happen. We refer to this as “exotherm”. This stage in the process is crucial to the chemistry of the coverstock and by controlling the peak temperature, heat rate, and cooldown speed we can manipulate the chemical porosity deep within that helps with oil absorption and displacement. This creates caverns of porosity and cliffs so deep which give this stateof-the-artshell the kind of cutting-edge traction that’ll leave you in awe. Enter: EXO Reactive coverstock.
