With the four options in stock shafts that comes with the 913 d2 driver, without actually hitting them, which is a best bet for me? My swing speed is 101-105, I weigh 145 pounds, my handicap is 6, and I don't have the availability to try out the different shafts. My birthday is on the tenth of october and hope I can make a education decision on the shaft I choose for my new 913 driver. I do like the look of the aldila, and I think I would like the equivalent of the project X 6.0 driver shaft that comes in the cally drivers. I love the feel of that that shaft. Any help is appreciated!
