Title: Rev Leverage Hole ?
Post by: Jeffrevs on January 29, 2004, 03:48:56 PM

Is this a positive thumb quadrant hole, and, what does it/or is it supposed to do ?

Thanks...

Revs the ball earlier.  In the classic revs leverage drilling the cg is down below the grip center line 1/2 the pin cg distance and the rev leverage hole is drawn almost 6 inches down from VAL.

I swear with this drilling I get two revolutions in the air before ball hits the alley(with almost no loft).  

Of course variations in between are permitted and just tweak how early the rev starts. The less down with cg and rev hole the less early!

REgards,

thanks, so the further the cg is below center line, and the closer to the thumb the x hole is, the earlier it revs ??
