Have you ever wanted to harness the power of a shooting star?
Roto Grip® has done it with the introduction of the RS-1. This new mid-price ball delivers unmatched performance in its class.
The modified Rotary III core has been encapsulated to lower the RG as well as raising the differential. This translates into better read in the body of the lane along with stellar energy retention down the lane.
The Sure Grip pearl reactive shell on the Roto Star provides modest length and volatile backend reaction on those medium patterns.
