cg has almost no effect on reaction in a high mass bias ball. as long as you take the end static weights into account and make the ball legal you will be fine. a pin up drilling may require deep drilled fingers. as for layout i like to go with a 4 inch pin to pap distance with the mass bias under the thumb. smooth and strong reaction. good luck.
