The Nomad pearl features the performance proven Rotary core found in the highly successful Silver Streak Line of bowling balls. This mid-rg and higher differential weight block was one of the best sellers ever from Roto Grip. The unique shape combined with the best coverstock technology of the time was elemental to that success.
Fast forward to 2009, we have taken this performance proven core and added a new coverstock to these balls. The Ultra Vision coverstock is bred from the original Sure Grip coverstock, but with friction enhancing additives that have given us great success with some of our other coverstock blends like the original Cytoplasmic, Cytoplasmic X and the recent Cytoplasmic XL. This combination of enhanced friction and performance proven core technology is sure to please.
