What width are your current bars? I have a set of 35cm Scattos and think they're great - the narrow width and the forward sweep of the bar does alter the feel quite considerably from a straight bar, so the setup will change a fair bit, but I do feel considerably more aero than I did on a 40cm straight bar.
I like the look of the Dolan Alpina sprint bars as well, though I anticipate they aren't as aero as the Scattos.
