## Description

Given the success of the RST™ Core (Roto Star Tour Core) worldwide, we felt it was imperative to create yet another outstanding option in this prolific series utilizing this dynamic Medium RG Asymmetrical Core.In order to create a ball reaction/motion different than the RST™ X-2, we felt that going with a more aggressive coverstock base material to read more in the midlane was indeed the answer without the ball reacting too early.For starters, we opted to go with 2-parts Pearl / 1-part Solid in this version of MicroTrax Hybrid in order to produce more traction in the midlane, while still proving plenty of reaction/motion down lane. From there, upon countless tests and studies, we felt our latest "4K - Fast" finish provided us the optimum reaction on the lane while still allowing for the coverstock to be dialed in even more for each individual bowler. This combination definitely produces A LOT more midlane traction in order to create a greater separation in overall reaction between the RST X-2 and the new RST X-3. It's OK, you can thank us later.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.MicroTrax™ Hybrid Reactive Coverstock: Our MicroTrax (Micro Nanoparticle Traction) Hybrid Coverstock creates a larger than average footprint in oil, while still providing above average responsiveness to friction down lane thanks to its overall chemical structure. This version of hybrid technology is far and away our most aggressive due to the nanoparticles helping to provide greater peaks and valleys in the overall surface profile. Bottom line, this coverstock technology just flat out crushes in terms of performance. Featuring a 100% nanoparticle load, this hybrid concoction provides midlane traction and response to friction while maintaining its surface profile over a longer period of time to ensure you get maximum performance each and every time. And just like the hybrid version, the hybrid version displaces oil at the highest rate of any of our pearl covers. Basically, think of it as added forgiveness on those not-so-great shots off your hand.
