BEHIND THE DESIGN:
Given success and popularity of the original RST™ Hyperdrive, we felt there was no better time than
now to create a follow up that was the ideal complement to the Roto Grip lineup of balls. In order to
make sure we got the ideal cover, we put the R&D Team and ball testers to work.
After multiple rounds of testing featuring both hybrid and pearl materials, it was a unanimous
decision that we roll with and introduce our newest formulation of pearlized material better known
as U-R1™ (ULTRA-Response version 1). Compared to previous nano-free pearl materials, this material
provides plenty of push through the front of the lane from every angle, while providing ULTRA
response to friction down lane no matter the style of bowler. Lets just say if you thought the original
Attention Star was out of this world... WAIT UNTIL YOU SEE THIS!
