When I decided to go custom, I went to the shop of a custom builder (Elliott Bay Bikes who builds Davidson bikes). After an hour of talking (and riding on a bike in a stand) I was most confident that these guys knew as much as most fitters and I was not disappointed. The minute I got on that new bike 4 months later, I knew I had done the right thing. GOOD LUCK!

ps I went custom because I got tired of doing things to my bike to help with my issues that compromised the bike itself!
