Total agreement that it's the fitter not the system. Go to three different systems and you'll end up with three different fits. Every single system out there relies on interpretation from whoever is doing it. Ask others about their experience with particular fitters as opposed to trying to pick the best system. Your fitter should chat you up and learn about your physical shape (mine went through a series of stretches to determine how flexible my muscles and back were and talked with me about my experience, goals, past history, etc) and learn about your needs. Some of it's obvious but sometimes it's not done. Anyone that simply puts you on a bike and starts adjusting isnt' worth your time. There are some folks with paricular issues like knee pains and foot problems that require real expertise, well beyond even a good "regular" bike fitter. Look around...chat people up...find a place with a good history and reputation regardless of the system they use.
