RST X-1
Tour players naturally tend to migrate to those balls that offer more core torque and continuous motion down lane with minimal deflection through the pins. It was that logic that led to the development and creation of the all-new Roto Star Tour™ Core—designed for Tour level players and those who aspire to score like them..

RST 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 really affect the bottom mass of the core. Thus, making this core a “Tour Level” type core design better known as the Roto Star Tour Core (RST™ Core).

MicroTrax™ Coverstock
The MicroTrax (Micro Nanoparticle Traction) Coverstock offers the optimum balance of midlane traction and responsiveness to friction thanks the blend of nanoparticles throughout the coverstock. This formulation maintains its surface profile texture longer to ensure you get maximum performance while displacing oil at an above average rate compared to other coverstock materials on the market today.
Engineered for Medium/Heavy to Heavy Oil Conditions
