I am trying to re shaft a Titleist 910 D2 with surefit adapter with a Fukijura Vista Tour 70 R Shaft (stock 46"). My question is how do I measure the correct length to trim off the tip. I want 44" length but I am confused. How do I measure. Do I measure straight up with the shaft or do I measure once i fit the shaft in the adapter and head and measure 44"? Any help would be appreciated.
