i have recently changed from stiff graphite (Graffaloy Prolaunch) to regular steel (TT Lite) purely due to accuracy. distance wise steel shaft would be lesser even though its regular. the weight actually slows the club head speed down and tempo.
there are a couple of popular steel shaft in the market...
TT Lite
Project X
NS Pro
there are all good, you just need to do club fitting to find out which best suites you.
