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.
RST™ Core (Roto Star Tour Core): Professional bowlers like to see continuous motion down lane with minimal deflection as the ball enters the pocket due to their rev rates usually being on the higher side. This logic was the basis of development by the R&D team as they looked to create a core that would maintain dynamics after drilling in order to maintain a higher level of core torque down lane. The larger mass at the base of the core does indeed create that. Especially since when drilled, the thumbhole will always end up in the void area not to affect the bottom mass of the core. Thus, making this core a "Tour Level" type core design.
eTrax™ PLUS Pearl Reactive Coverstock: Cleaner through the front of the lane – CHECK! Provides traction throughout the mid-lane – CHECK! The most responsive eTrax coverstock down lane we have ever created – CHECK! The eTrax PLUS coverstock material is the most advanced version of the eTrax chemistry we have ever concocted. After countless hours of testing on the lanes paired with mixing, re-mixing and adjusting in the R&D Lab, we found a way to enhance the overall performance of this material by changing ratios both up and down in the chemistry in order to create this overall “stronger” version. Thus, making this cover more aggressive and responsive than the original eTrax covers, but not as early and smooth as the MicroTrax™ covers.
