I just went through the club champion fitting for a driver and was pleasantly surprised with what they fitted me for because it was not what I would have picked. Club champion is a bit more expensive as they add on a few things like puring of shafts and so on. That being said I feel its worth it, my fitter was able to take my driver spin from 3500 ish down to roughly 2000-2200 and brought my flight window down considerably.

A lot of people swear by them, but they are a little more costly than other places. I went once for a driver fitting, and the fitter didn't seem too enthused, after trying a couple of head and shaft combos, he basically told me that was about the best they could do. It could have been just that fitter, but I won't go back.
