ShopTalk: demo clubs

[Scott Stephens]

I was wondering on what the consensus is for demo clubs for dynamic 
fitting?
Summit and Jackson recommend using 6 irons for fitting most parameters 
in "Total Clubfitting in the 21st Century". I've seen other posters who 
use 5 irons, or so it would appear.

I realize you need other clubs for fitting other things, but for fitting 
most parameters I'm interested in opinions on whether 5 irons or 6 irons 
would be better (or other)? Or does it really matter?

Thanks in advance for any responses

I think I'm finally sending this to the correct email. I hope you don't 
see 3 copies of this post. If so, sorry
