I guess I'll chime in with an opinion. I've got some VO Milan bars on my "townie," which have a little bit of sweep back. I wish I had a stem that I could put up quite a bit higher (like a technomic), because the comfort the sweep provides is wasted if there is any drop. I know super tall stems look goofy as hell, but the upright riding position really makes it worthwhile as far as comfort for townie riding is concerned.

Edit: I'm 6'2 and my townie is 62 cm with a pretty long TT. What I've found is good about having a frame that is a little too big for me is that I can keep the saddle a little lower, which in turn allows me to reduce my saddle to bar drop even more while keeping my leg extension appropriate.
