Also, "low tracker" is kind of vague. Any idea as to your actual axis point? Reason being, is that if your horizontal measurement is 3.5-4 inches over, then you could put the pin at 5-5.5 inches from your axis and be able to drill the thumb hole pretty close to the MB and not need a weight hole, unless the top weight is pretty high. Either way, you are probably going to need to drill your finger holes pretty deep if that cg marking is the correct cg. Also, have the pro shop guy check to make sure that cg marking is the correct spot.
Peace doesnt always have to be silent.
