A lot of people are going to tell you to go see a Titleist Certified fitter to determine the best shaft for YOUR game. I totally agree with that. People can give you their suggestions or opinions, but it doesn't mean anything if its not a good fit for you. Go get fit and get the best shaft for you... You wont be sorry that way

I agree, go see a fitter, but as a head's-up, the new Diamana D+ on the 915 is nothing like the new one on the 915. I think the Rogue shafts are more similar, but that is MY OWN opinion from hitting lots of them and I guarantee my swing is different than yours. 

I think there are a lot more good choices for shafts on the 915 than there were on the 913. I think Titleist did a great job with the offerings, but that means more work to decide which is best (but worth it). 

When I was fitted for my 915D2, I had thought that the Rogue black was likely going to be the shaft which I would prefer the best and provide the best results.  After being fit, it was clear that the D+ White 70 was the optimal shaft for my swing.   Difference was consistent direction, flight path, and roughly 15 yards more than the other combinations.  This also represents 15 more yards in comparison to my 910D2 with Project X-7C3.  Go get fit.

I had the same experience. Heard all sorts of good things about the Rogue but after looking at the numbers, the D+ was clearly a better fit.

Hi Andy,

I spent over an hour working with different shafts at golf galaxy. I'm 56yrs, old and can still get it. I went with tha alida silver rouge stiff. Worked on the simulator and it worked on the course. Best club I have ever had. Period. Godd luck with it.

Play Well,

Andy,

As most of the responses have indicated, proper fitting is the key as most everyone is different as it relates to swing speed, tempo, release (early, mid or late) and angle of attack.  Personally, I think the shaft stiffness profile is THE most important factor after selecting the correct head (as it relates to launch conditions).  In other words, if you swing at 80-90 mph with your driver you wouldn't want to be in an X-flex shaft and likewise if you swing 120 mph you wouldn't want to be in a R-flex shaft.  This is why most every fitter will tell you to play the most flexible shaft you can CONTROL.

The trouble is that there isn't a standard profile for R, S or X-flex so they try and accomplish a standard range based on shaft frequency.  Different shaft manufacturers have different criteria for the different flex designations.  As it relates to your question, the Diamana D+ has a high kick-point with a stiff tip and mid section of the shaft.  The Rogue Black will have a kick-point that is lower and as a result a softer tip section (softer than the D+ that is).  The important thing is that you get the correct stiffness/bend profile for the respective shafts that fit you and results will not vary tremendously.  For instance, you may find a 10.5° head with a D+ shaft gives you better results vs a 8.5° with a Aldila Rogue Black, or vice-versa.  This is why everyone is telling you to see a fitter because getting the right head with the right shaft (for that fitting day) is the most important selection you can make for your game...

Hope that helps!
