Im not sure which of these two shafts to have in my 915 D2 9.5°
Diamana s+60 5ct reg flex. Weight 60g, Tip .335 inch, Torque 5.3°, mid kick point
Fujikura e360 fit-on reg flex. Weight 66g, Tip .335 inch, Torque 3.8°, mid kick point
I was originally fitted for the Diamana in my D3 9.5°.
I have a swing speed 85-90 miles an hour.
