          R2X Pearl Coverstock
Type
              Pearl Reactive
          Slightly more aggressive than the famed R2S coverstock material, the R2X is right in the middle of Storm’s reactivity chart. It is the perfect balance of porosity and durably. It doesn’t grab too early, but doesn’t go too long either. Its versatility can benefit numerous bowlers of various styles.
Centripetal Core
 
Custom-engineered for the player who desires low, stable spin with forgiveness, the Centripetal Core features a center of gravity that is extremely low. The innovative cascading channels engage the circumference of the weight block and maximize mid-lane control with a smoother change of direction downlane.
