After putting it off for years, I only regret not having done a full-bag fitting years ago. I did most of my fitting with Alex in Deerfield. When I came back to do woods and wedges, he had moved out to Schaumburg. I was so pleased with the clubs I had gotten; I made the 2-hour round-trip in order to finish the fitting process with him there. There's no high-pressure pitch to force you to buy from them. If you do (I did), it's because you know the quality of the build-outs will be as good as the fitting process.
Whether you're a scratch or a 25, it's worth it.
