I know the hole 2" down the VAL is used to move the PSA but what does it do to core dynamics compared to P3/P4. according to this chart from storm it increases differential. http://www.stormbowling.com/drill-specs/PSA_Lightning_Stikes.pdf Has someone created a chart that shows the differences between (2" down the val) and P3/P4?

Very similar to P3, but will move the PSA a lot, which strengthens the effect of the balance hole and lessens the drilling angle. It's the only way to get true small drilling angles with a symmetrical ball. MathIsTruth will tell you he's seen PSAs move as much as 5" using this system.

thanks guys. I didn't expect a response so soon that's awesome. I agree that makes dealing with symmetrical balls easier to work with. I have a hard time finding a proshop with a determinator near me unfortunately. I would love to experiment with one someday
