The Roto Grip Halo Pearl is the perfect compliment to the original Halo bowling ball. This ball utilizes the same proven Centrum Core that was introduced with the Halo but a completely different coverstock. This ball is wrapped in the eTrax-P18 Pearl Reactive coverstock causing it to move at a different part of the lane. This ball offers a footprint in oil while still producing a responsive reaction to friction when lane conditions are medium to medium/heavy oil.

eTrax-P18 Coverstock
Type
Pearl Reactive

With the original IDOL™ showcasing a solid cover built for heavy oil, we knew we needed something to compliment it. After a couple rounds of testing various pearl materials, we finally dialed in combination of the footprint in oil and responsiveness to friction. That is how the eTrax-P18™ Pearl Reactive coverstock was born.

Centrum Core

It took more than a year to develop this unique-shaped core, which increases its rotation/continuation once the ball is in motion.
