I have a friend who is a full roller and he is having problems getting the Rule to hook at the pins. Seems the ball just slides by or hits weak. I told him since he throws medium speed (15-16 mph) with LOW revs he might have to change the coverstock. I was thinking 600 or even 400 grit. Does anyone know what the out of box grit is?
Thanks
Robert
