OK, let me hear how to add weight to the grip end of graphite. The Tour Lock system SKU: TLCP8V I use for steel won’t fit graphite I.D. 1st customer asking MOI with graphite. I was thinking of adding an additional 2 gram piece of tape under the grip on the backside. Also thought using the cork plug soaked in epoxy.
I use SKU: GW1118 most of the time for tape. I believe this is the heaviest tape out there.
I’ve used the butt weight ports with lead or tungsten powder. I just sand the port to fit graphite shafts. GW part BWP. Take a look at GW0113 if a longer port is needed. I’ve read of other builders who use bolts for counterbalancing, though I’ve not tried this method.
