If the pin-CG is around 4", I'd place the pin just above the level of the ring finger but at 4" from your PAP. I'd place the CG about 4-4.5" from your PAP,a s long as it did not wind up too far below the midline, maybe 1" max. Try to leave a much side and top weight as you can to increase reaction. Put any weight hole below your PAP, in normal place, on line fron grip center thru CG.
