The Roto Grip Halo Vision is versatile high performance bowling ball. This ball utilizes the same proven Centrum Core that has been used in the previous Halo balls but with a hybrid coverstock. This ball is wrapped in the eTrax-H19 Hybrid Reactive coverstock which was designed to give more surface roughness while maintaining its responsiveness to friction on medium/heavy to heavy oiled lanes. This ball is cleaner through the front of the lane but breaks a little early but can be easily adjusted depending on the bowlers needs.

Produces more surface roughness without compromising high response to friction down lane.

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.
