Confused about shafts - Project X and Rifle....

Things got complicated a long time ago mate. I love all the shaft discussions, I can add nowt to them other than to say my clubs have shafts, I swing them and hit the ball - the ball goes.
Hardstepped, softstepped - WTF? Mine are steel and quite hard, steel is hard, I though it was one of it's main properties and why it's so popular...

Anyway, that's about as much as I know - about as much as I do about ball flight laws... Do I care? Take a guess :thup:
