AMAZING!!!
I got this fitted to my hand (finally, [fingers feel wrong thumb feels wrong, thumb STILL feels wrong, etc.]), and just shot a series on it. I could throw it ANYWHERE on the right side and it would ATTACK the pocket! I'm not talking a curve to where it's supposed to be, i'm talking pure skid-snap hard into the pocket!
Anyway, it's a good ball for someone who's been bowling on brunswick PG's forever.
The pin is above my middle finger, and the CG is below in the middle. On fingertips, too. Can't tell you much more; I got no instruction sheet with all the drillings with this.
Poly-p man
Oh, and DON'T use this thing on oil- you know that skid-snap? This is skid-gutter.
