I've had a lot of success with the standard rico drilling, however in heavy oil I actually find that this drilling goes too long for me. Would I run into static weight problems if I were to move the pin an inch up and an inch right (I'm a righty), and would doing this still retain the same ball motion that I like?

You shouldn''t have any problems. Just depends on the TW of the ball and pin distance.


My favorite is just moving everything 1" closer to my PAP.
My PAP is 5.5" across and this puts the pin in the 4.5" range.

It gets the ball into a roll a little sooner and works great for when My other ball on the same pattern is going a little too long and not carrying the ten pin. I can switch to the Rico with a shorter pin to PAP and move in a little and get a great reaction.

It shouldn't. This pattern isn't much different from most leverage patterns and when you compare a ball on the Rico Pattern to the same pattern with everything moved over an inch you will notice that the biggest move is the pin. The cg, mb, and weight hole are only moved a little.(if both bowling balls are identical in pin length) When I have the two side by side they look almost identical except for the pin.

Surface is the largest component of adjusting overall reaction and easiest. Also if the flares are too tight the oil stays on top on the rings longer creating too much length.
You can use surface and weight holes to adjust reaction easiest.
