DP3,
Actually the cg is mismarked. The pin should still be approx 6 3/4 from the mass bias. The mass bias on the Response should have a little pin in it. This should be constant.
Drill the ball the way you want to. Put the pin where you want, and the mass bias where you want. Adjust the finger hole depths and extra hole location to adjust for where the cg is. Also, check to make sure the cg is correctly marked on the ball before drilling.
