RST™ + A.I. Core Technology
Boasting the same higher RG asymmetrical Roto Star Tour (RST™) block + A.I. Core technology as the original RST Hyperdrive, the general core motion is the same. While its RG value helps promote length, the dynamic offset between the top and bottom discs promotes accelerated levels of torque which translate into change of direction down lane for all styles of bowlers.
U-R1™ PEARL REACTIVE = ULTRA-RESPONSE 1ST EDITION
Our newest formulation of pearlized nano-free material provides plenty of push through the front of the lane from every angle while providing ULTRA response to friction down lane. Without a doubt, every style of bowler will benefit from having this type of forgiveness down lane.
