Summary: Demo'ed 910D3, and D2 against my Nike Sumo SQ. Decided after swinging the D3 multiple times that my Sumo and D2 felt like I was swining a shovel. Bought the D3 and actually increased my %fairways hit from 48% to 54%. So all in all no loss of control and gained about 10 yards off the tee.
Conclusion: This is an amazing club. I initially was not a technology believer thinking that USGA would not allow the clubs to get better & better. So, I figured I would wait. However for Christmas, I received the titleist 910 D3 and 910 3 wood.
Conclusion: Absolutely love this club. When I bought it I had them set it on A-1 and I have not moved it. I'm hitting it so well I don't want to mess with it. I went in with the thought of the Aldila shaft as I have had good success with those in the past but I tested the Diamana Kai'li and the results were...
Conclusion: Have about ten rounds under my belt with this driver -- 8.5 with Project X shaft. I was fitted for this club and it seems to matter. I never would have looked at an 8.5* driver, but that is what the fitter said and I figured if he was wrong, I could adjust the loft to a 10.
Conclusion: As i own the one of the white heads mentioned above, i think i agree, on sweetspot contacts i still think i have the best option ( tm R11 TP ) man this club feels good, on the other hand if i don't get it on the sweetspot i lose the forgiveness i was used to in my cobra S9-1.
Conclusion: Eric: Thanks for your great reviews. Your review of the Mizuno MP-630 Fast Track driver had a lot to do with my purchasing one. Did the 910D3 knock the MP-630 Fast Track out of your bag? Rick
