New Roto Grip Idol Helios & Rubicon UC3 Bowling Balls Reviewed by Bowlers Rant

On the inside you will find the low RG, higher differential symmetrical Ikon™ Core made famous in the original IDOL™. But on the outside, it’s the coverstock of this ball that is going to help you outshine and outscore your competition. Our newest coverstock technology known as XtremeTrax™, features “chemically charged” nano particles which create the highest amount of responsiveness to friction we have ever seen from a nano particle material. But don’t worry, the nano particles will still provide plenty of traction in oil before the “chemical charge” kicks in down lane to provide more change of direction than the original IDOL before it.

The Rubicon™ UC3 (Ultimate Concept 3) takes Tour Level performance to a whole new level. We first focused on core specifics and decided that the mildly asymmetric Rondure™ Core was the ideal core shape in order to generate adequate flare.
