I appreaciate the response. This is way more than what I expected. I don't know what you mean by intimate? Do you mean if I'm comfortable with my swing or do I know my swing? I did do a launch monitor and all that good stuff before. Unfortunately, the only thing I could remember was that my swing speed was around 105. I forgot all the other details like my ideal launch angle, ball spin etc.
On my old Cobra driver, I had a harrison 2.5SL shaft and got great results. Only reason I got rid of it was because I really wanted the bigger 460cc head.
