Can anyone give me an estimate on where the Mass Bias on the Trauma Response is in relation to the pin? I am getting a mismarked one and I don't think the usual 6 3/4 from the pin through C.G. is the correct placement on this ball. Could someone let me know or let me know if they've ever drilled a ball with a mis-marked mass bias and how it reacted?

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.
