So, last winter I purchased a the new 910 D3, I was fit at a Golfsmith and based on my swing spec's then they told me I was in the window for an extra stiff shaft. This may have been a mental thing, but I felt that if I went into the x category I would have to be swinging hard all the time in order to get the shaft to work for me. So, they told me if I really felt that way it was a toss up and my choice between the Project X or the Diamana Ahina (the black one) in an extra stiff.
After playing for the summer with the Project X, I've made some changes in my swing that have made my swing faster and more efficient. So, I'm not sure I'm getting the same performance with the Project X that I was originally. How should I go about getting the Diamana Ahina X into my driver? What types of cost am I looking at for this modification?
I'm 6'4" and I have a fairly steep swing so I generate a lot of back spin. So if I can keep the spin down that would be where I need to be.
Thanks in advance
