I have some aero handlebars (Easton EC70) and I love 'em - they're a clean, kick-ass look and I find the flat tops to be comfortable, even bare-handed (it's a position that I use quite a bit when riding solo, but I don't put a lot of weight on my hands, so YMMV). The only bad thing about them was the install - getting hydro lines and shift cable housings through them was a pain in the ass. If you don't have to deal with that, all the better.
