If you apply a constant amount of energy to the mass of the clubhead, the
maximum energy transfer happens when the mass of the clubhead and mass of
the ball are equal. But the reality is that there is no way that you could
move your arms that fast (using a club of legal length).

Remember that if the shaft is heavy, the clubhead must be light--and
visa versa. Club designers know there is a very finite total weight
limit for each club. Since the weight of the clubhead is the whole
enchilada in imparting velocity to the ball-- we should endeavor to
use the lightest possible shafts-- graphite. It is a wonder to me why
anyone except touring pros with 130 MPH clubhead speed swings-- play
anything BUT graphite. Just silly--ego, etc. I know I and every
friend who has alternated says they lost at least 10 yards per club
with steel over graphite. Why? Why force yourself to swing out of
your shoes trying to hit a 7-iron 150 with a Mizuno MB and Rifle 6.5
shart-- when a nice smooth swing could do it with a graphite cavity
back BB or equivalent? I gotcher ego right here.


I don't think it's ego, at all. I used graphite shafted irons for several
years and then tried, went back to, as it were, steel and found very
little loss of distance but a _whole_ lot increase in accuracy. Where
before, with graphite, I'd usually hit less than five greens in
regulation, with steel I'd hit anywhere from 8 to 12 pretty consistently.
Where before I'd be "lucky" to have one birdie a round, now I consistently
give myself three or four makeable birdie putts a round and can count on
making one to two--as putting is my biggest metric to how I score.

And back to the distance thing...I used to hit my graphite shafted seven
iron 155-160 and now I hit my stell 150 to 155. So if I need 160 I just
hit a six. Big woop.

And another thing...I've never had a steel shafted club break but in the
five or so years I used grahite I had two short irons do so and had to
replace the shaft. And I never--well hardly ever as I don't like to say
"never"--see gap or sand or lob wedges with anything but steel shafts.
They're just tougher and more consistent.

Ego can work both ways--why keep hitting a graphite shafted 7-iron 160 but
not on the green when you could use a steel shafted six and put it _on_
the green?

As usual your six or seven will vary.

Oh wait, my bad...this is, after all, rsg--er, uh why hit a choked down
graphite shafted 9 iron 195 when you can use a choked down steel shafted
8...er, um, you know the drill.
