I have the 910 D3 with the RIP shaft. Love it!!! First Titleist driver I have hit well and liked the feel of since the 905. I previously gamed the TM Supertri. when I decided I wanted to get a new driver, I hit everything, and I mean everything in my search. The 910 D3 won out.
I really like the look at address with the D3. Interestingly, my numbers were pretty similar with the D2 head with the same shaft but liked the look and feel of the D3. Spin numbers were 2700 ish with the D2 and 2400ish with the D3, launch angle within a degree and distance within 3 yards with the D3 being longer.
Can't wait for the weather to break to get this thing out on the course.
