When 913 launched I didn't see much advantages to change, but with the new 915 I did. And with BIG improvements. Not only do I gain distance, also the dispersion is much better. Playing of 12 my task to improve towards single digit is getting a much tighter dispersion from my driver and more control on my hybrid. Both are the case with the new 915's. On top of that I pure the fairway wood 235 yards (gaining 15 yards). Also driver and hybrid carry distance have improved some 10 to 15 yards. All in all I am very happy with the change. 

After careful consideration I went for Diamana S+ Blue in stiff for all (spec below). Much better feel compared to the Aldila offering which I consider a bit harsh, unless you hit the sweet spot over and over again..... but who does?
