I just went through 3 iron fittings:
Golf Galaxy - the fitter was actually great but they simply did not have the options I needed (long shafts) despite me calling to confirm they'd be able to accommodate my 6'7" needs. The fitter refunded me and recommended two options - CC and Westfields.
Club Champion (Fairfax) - tons of options and the guy was okay. But it felt like a sales exercise, not a fitting, and the clubs were ridiculously priced. It didn't leave me feeling confident.
Westfields (Ken Farrell) - much more what I was looking for. Lots of options but
