## Description

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 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.
