Go for it. Hugh (True North) is building a touring bike for as we speak (well type). I have followed Hugh's career from the days when he was working out of a shed on his parents farm with wood heat. Where else can you get a frame designed and made by a Mechanical Engineer who is a bike guy? Hugh's welds are some of the best I've seen.
The fitting part of the "custom bike" is also great. I had the advantage in that I can go to the shop to be fitted as it is only about 1.5 hours away. I'm huge and tall and Hugh had no trouble fitting me and finding "big" tubes that would hold me. Ted
