Roto Grip UFO Bowling Ball

This ball was designed to be the perfect complement to the original HALO. Sure, both balls feature the same core. However, the big difference is the coverstocks. Wrapping this core with the eTrax Pearl cover creates motion in a completely different part of the lane. If you were to drill a HALO Pearl and a HALO the exact same, you would see approximately 6-8 feet more skid, which transcends into A LOT MORE BACKEND!
