I have switched from a png G10 Diamana 63S, at 45.75 inches to the 910D3 Kai'll 65S at 45 inches. The specs on both of these clubs are suppose to be a D3 swingweight, putting both clubs in the hands and comparing, the 910 really seems to be heavier? any thougths and what would changing out the 7 gram weight in the 910 head to a 5 or 2 gram weight, due to the swingweight?
