I flew out to San Diego for the day and did the fitting in their studio. I personally don't think it's worth it. I've had multiple putter fittings and I don't think their method was particularly special. Also, I didn't putt any better w/ their recommendation. However, if you do the fitting, you are able to custom order a Circle T to your specs. The one the guy showed me was c$2k, but they go up from there.
I just bought a Directed Force 2.1. I probably would recommend that over anything, but I suck at putting.
