Yes, I just got a chance to test the 915.  Much better than the 910.  I have been hitting the 910 for about 3 years now and it did not take long to see and feel the difference.

For one, I was not able hear the difference in sound that some people were talking about.  Might just be me, but it did not sounds much different.  But then again, the sound is the last thing that crosses my mind.

The spin rate was really reduced and I could easily tell the difference.  Even though they did not have any X-stiff shafts for me to try, I was still able to keep it under control.  I was constantly hitting it about 295 with a stiff in the Rogue and Whiteboard.  

I will say this, before I buy it, I will go to a fitter that actually has some x-stiff shafts and find what suits me best.

If you have any specific questions you need answered, feel free to leave them here.  A lot of us will be glad to answer.

I have a similar swing speed. Mine is in the 112-117 range. I have been fitted on numerous occasions to an x-flex shaft.

It helps me keep my spin down as well as tighten up my dispersion. The x-flex also "feels" better to me. I don't feel like club head is trying to keep up with my swing. Some people with fast swing speeds like to use a stiff flex because it gives them better feedback on miss hits. (Not that we ever miss hit balls.)

Test both (x-flex & stiff) if you have them available to try. Then, look at the numbers and make a decision based on what you think suits your game best.

Hope this helps, Justin

[/quote] Go see a certified fitter, please.  They will are the experts and will set you up correctly to fit YOU.  Everyone on the forum has individual specific needs, so please go get it from some who can do it right the first time......

I was at the driving range the other day and the Titleist Rep. was there with the head pro hitting the new 915 D2 & D3. I was able to hit the new D3 in 8.5* with the Diamana Blue in stiff flex. The shaft was a little light for me but the ball absolutely jumped off the face. I cannot wait to hit it in the spring when the pro gets his fitting cart. The club head is very appealing behind the ball at address too.

Justin S: You have to wait to be fitted by your pro until the spring?  Most fittings are being done now for the release date on Friday.  I was fitted and pre-ordered on October 30th and will be here on Thursday.  

I could go to my local Golf USA store and get fitted today if I wanted. Not sure if my pro is not taking appointments til spring or, if he won't get his fitting equipment til spring. Either way, I probably won't be ready til spring to get new equipment anyway. Looks like our fall is over here in Kansas now. Mother nature hit us with an icy chill reminding us that winter is near!
