I sure hope that Titleist's next drivers have some low spin technology. I currently have a 913 D2 driver and in the last 6 months went to 2 separate fitting days for a 917 D2. Both times we could not get my spin rate below 4000 rpm's. Trackman had my swing speed at about 80 mph. We tried every combo of length, loft and flex, to no avail. I'm sure that my swing speed is lower than most TT Members, but it is what it is. I have tried other drivers and one in particular was giving me 10-15 yds more carry and 10-12 yds more roll and 800 rpm's less ( Trackman numbers, outdoors ) with a 44 inch shaft. I'm not saying which because I'm not going to tout another Mfg. on this site, but it's hard to argue with the numbers. I'm going to hold out for a while and see what the Titleist R&D folks come up with as I'm sure that a new driver is coming soon.
