I don't know about "player" shaft, but I used to use a steel shaft in my 3 wood and have switched to the stiff 757...it just feels great...I don't know about loading and unloading, but feels more stable than my adila nv 75 and shoots the ball out well with an easy swing. My swingspeed? I don't know...I average 260 on drives with the odd one going 220 or 290 depending on many things (this includes roll as I can't see well enough to determine carry landings). It resembles steel feel without the weight which I like and does not have the torque of a lighter weight graphite shaft which I find distracting.
