Given the continued success of the RST X-1, we 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, we determined that the eTrax pearl material gave us the type of reaction we were looking for, but we 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 we 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.
