I think it is more a different way to layout your ball.  I have read Mo Pinel's article on the subject and it seemed interesting.

it might be an easier way to drill and compare bowling balls. if you want ball A to have one type of reaction and ball B to have a different reaction you just change the angles. i tried it on a couple of balls and it will work. you still need to know the bowlers pap. and now instead of saying i put the pin above or below the fingers , i can say the drilling angle is 35deg with a 3" pin,(or whatever deg. angle and pin length you use). is it better? i do not know. pin and cg still wound up in the same places as if i had used the " old way " to lay out the balls. like i said, only used it a couple of times. hope this helps a little.

I have an ignorant question or two.

1) The closer a pin is to a bowler's VAL, is has more movement in the backend, correct?

2) What would happen to a drill where the pin is beyond a bowler's VAL?  I have an old ball I had label drilled before I got real serious into bowling, and the distance from pin to CG was enormous and it's easily past my VAL. Looks sort of like this:
----------o

----oo-----
-----c-----
-----------
----o------

3) Assuming that question 1 is true, would this drill be possible?  It's probably really similar to a RICO drill, just modified:  put the pin in a spot that's equidistant from the VAL if you were to draw the VAL completely around a bowling ball.  Now that I think about it, depending on PAP it's probably nothing like a RICO drill.  But would that drill create the smoothest reaction possible for a ball?
