The 900Global Volt upper-mid performance bowling ball uses the S72R Pearl coverstock which is the S72 Pearl coverstock with a catalyst added. This coverstock was designed to balance the ball's traction in oil and increase its performance at the backend. The Volt uses the Charged Symmetric Core which has a flip block on the bottom that will increase the change of direction at the breakpoint.
How is this ball compared to the white hot badger? Should I expect more traction from the S72R cover tan the S71?7/17/2019 - By Ismael
The coverstocks are numbers to show their strength so the S72 is stronger than S71 if they have the same finish. You also have to factor in the weight block too but just going from coverstocks the S72R would be a little stronger than S71.7/17/2019 - By Bowling.Com Staff
