My axis is 6" Right and 1/4" up, but on plastics and pancake cores, I'll typically clip the thumb hole almost the entire lane. To avoid tracking over the thumb on pancake core balls (I have a Black Sanded Scout) I have the pin/cg 3" right of grip center and 2" up with an x-hole 1" past my PAP on a line from the center of grip through the VAL. It flares about 2" with about 1/16" - 1/8" separation between the oil rings and moved my track about 1/2" off of my thumb.
