My swing speed is 105-110. I used to swing the 910 D2 with the Aldila RIP XS 60 2.7 shaft. Liked it, but went through a swing change and am not swinging as hard anymore. I recently bought the 913 D3 for more control, and it has the Diamana 62 XS shaft. I'm not getting consistent strikes with it, and at times I am snap hooking it. So I'm losing confidence in it. So my question is, what do I change? The head back to D2? The shaft to a S? The shaft to a different manufacturer? Kick? Torque? Or a combination of any of these? Btw, I like the new swing with every other club in the bag so I am not changing that.
