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!

 Key Features:

• The RST Hyperdrive Pearl is a pearl asymmetric option that designed for medium to medium/heavy oil conditions.
• The ball is finished with Power Edge™
• Core: RST™ + A.I. Core – Same proven core that was used in the solid.
• Coverstock: U-R1™ Pearl Reactive – NEW pearlized reactive coverstock. It’s nano-free that creates ULTRA response to friction down lane.
• This combination of Core & Cover generates ease of push through the front of the lane, while providing a strong, responsive, and continuous move at the breakpoint making it ideal for all styles of bowler from a variety of angles on the lane.

Plays Well When:

• RST™ Hyperdrive – is too early and something cleaner with more reaction down lane is needed.
• Attention™ Star S2 – is too early and something cleaner with more reaction down lane is needed. Attention™ Star – isn’t quite enough down lane or through the pins.
• Gremlin™ - isn’t quite strong enough and a stronger core and cover combo is needed.
• Rockstar™ - is too early and something cleaner with more reaction down lane is needed. 

After dominating the lanes at every level around the globe, we knew the follow-up had to be something special. It had to align with not only the original Attention Star, but it had to align with the rest of the Roto Grip product line as well.

In our first sequence of testing, we tried multiple coverstock materials to determine where the proper motion was to take place. It was in sequence two of testing that the eTrax PLUS hybrid cover out-shined the the others. It featured enough grip in the midlane without being too early, while providing plenty of recovery down lane like its predecessor. And that my star gazing friend is how the Attention Star S2 (Sequence 2) was born.
