Roto Grip Torpex Bowling Ball Core
By placing the TORQUE SPHERE just above the inner equator of the TORPEX Core, we found that not only did it create the lowest RG symmetrical Roto Grip part ever, but it also created a higher differential which translates to more overall motion and less deflection through the pins.
Core Type - Symmetric
