I was recently fit for 913 D3 9.5 degree loft with a Diamana blue shaft in stiff flex by my local PGA pro at the course I regularly play. I could not be happier with the fitting experience. My pro allowed me to demo the driver with several different shafts both on the range and on the course. When I narrowed it down to two, the pro went with me to the range and we compared them together. After about an hour we of hitting both shafts we both decided the Diamana blue was the way to go. I am not a big guy, but I was regularly getting a 245-250 yard carry which was easily 10 yards longer than my 910. I was able to take the driver out on the course for a quick 9 holes yesterday evening and had my best driving day in a long time. I could not be happier with my new addition to the bag! It is true that titleist makes the best equipment available and I will definitely continue to be loyal to the titleist brand!
