Magic Gem
« on: October 20, 2023, 10:26:06 AM »
The Roto Grip Magic GEM: a captivating and powerful bowling ball. Roto Grip combined the MicroTrax Solid and MicroTrax Pearl components to create the MicroTrax Hybrid Coverstock, resulting in an exceptional hybrid high-performance ball. The Defiant LRG Core, originally featured in the GEM, adds remarkable style and performance to bowlers of all skill levels. Its unique density composition makes it the fastest-revving, strongest-continuing, and lowest RG asymmetrical core in Roto Grip's current lineup. This coverstock technology excels in performance, boasting a 100% nanoparticle load for midlane traction and friction response. It maintains its surface profile longer, ensuring maximum performance. Plus, it excels at displacing oil, providing forgiveness for less-than-perfect shots. Designed for medium-heavy to heavy oil conditions, the Magic GEM is a valuable addition to this series of balls, complementing the GEM and Exotic GEM without overlap.

I am a higher speed, rev challenged 220-250ish, high tilt, high rotation, and super low track player. I drilled the Roto Grip Magic Gem  5 x 3 x 2 using Storm VLS and my axis point is 3 ΒΌ right and 7/8 up. The Roto Grip Magic Gem is an asymmetric Hybrid reactive piece that I really like medium/high volume patterns. The low RG and big diff gives this ball high flare potential when I need something to be revving, strong, and continuous.
