Roto Grip RST X-2 Bowling Ball Features:

Given the continued success of the RST X-1, Roto Grip knew the next ball in the series using the Roto Star Tour Core was going to need a special coverstock wrapped around it as well. So, after countless tests involving multiple players of different styles, they determined that the eTrax pearl material gave us the type of reaction they were looking for, but they wanted something a little more while still using that same chemistry. So, the R&D team went to work changing the ratios and other variables until Roto Grip settled in on the NEW eTrax PLUS Pearl Reactive formula that provides a larger footprint throughout the entire lane without reducing the responsiveness to friction down lane. Creating yet another viable pearlized coverstock option for the Roto Grip family of balls.
