This is a shaft made mainly for smooth tempo-ed swingers. Its stable in the butt with a soft tip and has the A2 technology which allows the shaft to return quickly giving you a tighter dispersion.
I have one in my driver. My SS is 95 mph and I left it at stock length (46.5") as I am 6'7". I like to think i'm a smooth swinger but I would guess I'm borderline agressive. I like it.
