An old friend of mine, Arnie Goldman, invented and patented this device.
It makes your grip interchangeable and fully indexable, which gives the bowler, the ability to change ball roll, through change of pitches.
Has anyone tried the Perfect-a-Grip?
I contacted Arnie, he said there are a few drillers in Detroit that carry the Pefectagrip. There were 2 in the Chicagoland area.
I'm thinking of trying his system.
