Ok, im not good with my technical stuff.  I have lots of revs, slower speed.  I had it drilled with pin about a half inch to the right of ring finger and the other cirlular thing in the middle of my palm.  I replaced a Roto Grip Fuel, so the reaction was totally different.  It hits like a truck!  Hooks alot more than I was expecting.  Even with the skid/snap I only left 2 splits and 1 ten pin.  Didn't shoot real high, but I was trying different lines, and just playing with the ball.  I would definatley recommend this ball to anyone.  Maybe use a little bit tamer drill, but it's the best ball ive thrown in quite some time.
