Regular flex CS Lite. Some other things about my game that may shed some light. I got a new driver at GG last spring. I believe my SS was just below 100, and that is stiff flex (Cobra F Speed). Per my new GPS, a well struck drive was 225, and 250 was the best this past weekend on a cold day. Last summer, my 8 iron distance was around 145, and 7 iron around 155. However, I could not maintain that yardage gap with the long irons. Based on 10 yard gaps, I should be able to hit my 3 iron 190-195, but I would use that for around 180 maybe (I don't bag it usually).
As far as swing, I generally take little to know divot, which may change as I am trying out the Stack and Tilt.
