Are all of the 910 D3 heads regardless of what shaft weight they go into the same weight? Reason why i'm asking, i'm going to be ordering a 910 D3 with the RIP 70 and wanted to be sure that you were going to be putting in a "lighter" weight head versus if I was ordering it stock with the RIP 60 shaft. Silly question, but want to make sure. I prefer a heavier swing weight.......which brings me to another question. Can I order the 910 D3 with the RIP 70 at a specific length and with a specific swing weight?
