I dont have the time to build myself a touring bike and I'm am wondering about the pro's and con's of getting my touring buke custom built vs. buying something off the assembly line at a bike shop. Any opinions? I am leaning towards a shop that does custom bikes using a surly long haul trucker frame. As I don't know much about the things to watch out for in individual bike compenents for touring. As in which componenents are more suited to a touring bike, if that's even an issue. As well the guys at the bike shop don't tour themselves. I'd assume they would know what components to look for in a touring bike but yeah... just looking for some feedback.

EDIT: I just realized what you meant by "custom." Oops. My bad.
Off the line can be ok (great even), definitely, but make sure you know a little about all the components, etcetera first. As it stands, your question could go either way, depending on the bike and the needs of the rider.
