Thanks for the replies everyone! I feel better about trying to get to know this twitchy beast.

I'll ride it around tonight, and down to the LBS tomorrow. Maybe I can work out some of the fit problems, and worst case scenario get mustache handlebars.

I still think it's funny I can go to store, get fitted for a custom bike, and still prefer the vintage beater I bought with no more thought than "it's pretty!".
