Best thing would be to test ride a bike with them and see if you like the ergonomics of those things, because they're all flat on the top. I took a Look bike out for a spin equipped with a Cinelli Ram, and aside from it looking really cool, I really didn't like the fact that I couldn't grip the tops of the bars (where my hands spend most of the time anyway) like I could with a round profile. Also, take into consideration that guys that have their own signature model like Oscar Freire don't even race on them, probably due to the fact that those bar/stem combos are surprisingly flexy compared to the stiff, positive handling of a traditional 2 piece set up.
