Thanks Ric. I don't mean to hijack this post but hopefully it will help others too.
As I get older my speed diminishes. Right now I am 14mph at the pins (Quibica) with 300 rpms and 25+ degrees of axis tilt. My pap is 4 1/4 over 3/8 up.
I am forced to stand as far left as I can and play as deep as I can to keep my ball in the oil as long as I can. I find that "weaker" balls will hook way too much for me in the back so I tend to drill a stronger ball with lots of polish and very weak pins, in the 5.5 pin to pap range. While I can generally be in the pocket with this the ball doesn't seem to finish well enough playing this angle to consistently carry the 10. I was just reading on BowlingChat that if using an asymmetrical with a pin in the 5 to 6" range that when it comes out of the pattern it is in a forward roll and this pin to pap distance is better suited for someone playing a more down and in type shot, not a deep angle. It went on to say if you wanted to play a deeper angle then a pin to pap of 3" with a large drill angle would be the way to go.
This is what I'm trying to understand and why I was so interested in this post about pin placement and axis rotation, etc. I was always under the impression that a 5 to 6" pin would allow for length (less flare) and a strong backend reaction? That's what I'm trying to achieve. Any thoughts Ric?
