both my girlfriend and i ride flat bars. I actually liked them better than the drops. my back would end up hurting after riding the drops for too long so i ended up riding the flats alot. So i figured why not get all flats. I dont think i would like risers too much though. too much riding in the upright position make s me feel like im riding a hybrid and not going fast enough.

Check your local bike co-op, thats where i picked mine up at. They were like 5 bucks. Then all you haveto do is chop em down.

Plus, depending on your bikes geometry, with flat bars you might be able to spin your front wheel 360 while riding and chicks always dig that!
