I have a custom Waterford with S&S couplers. It travels at least once or twice a year. As a small rider, your packing will probably be easier than mine (my seat tube is 58cm). The first trip was scary -- ?could I get it put back together? ?what if something went wrong? Now, I'm pretty comfortable with the assembly/disassembly.

I love the ride of the bike and it fits me well. Waterford is a steel bike. When I first starting looking, I wanted to go Ti, but the steel rides well.

Note: Terry's semi-custom line is made by Waterford. That might give you a slightly more cost effective solution.
