Scott will say spin it on a DeTerminator first. I would agree. But Jason is the man you should ask.
As far as I know, the mass bias is 6-3/4" left and right of the V at 90* of the pin to 'V' line.
In most of the pics I've seen, The 'V' is closer to 4" right of the thumb holes, putting the cg's right also. On my ball, the V is 2" right of the thumb. That, along with a short pin and low top wt, made this ball not roll like I had wanted. But we got it right with a balance hole in the P-3 location. Matt in Ohio spun his on the DeTerminator and found the PSA left of his thumb hole. He added a P-3 hole and the PSA moved to the right of the thumb. His also rolls much better now.
Please lets us know how yours is.
As for the gradient line. You go from your thumb hole to the PAP, then up the VAL.
If you didn't like that strike, just watch this one!
