Well with that long of a pin, a skid flip drill won't be a problem.  The problem with that ball is the top weight.  You are either gonna have to have the pin 5 inches above the midline, or go 4 inches, and drill the thumb extra deep.  The cg is gonna have to be kept on or just off the centerline.  I would go 5 1/2" from your axis, 4" above the midline.  Drill the fingers shallow and the thumb deep.  If an extra hole is still needed to take out thumb weight, put it 2 1/4" down from your PAP on your VAL.  Make it a small, deep hole.  This layout will give you a big skid/flip reaction, especially out of that ball.
