I like moustaches for my fixie; they give great torque for climbing and a decent aero in the front part. For me, however, they get uncomfortable after a few hours, which is at least part of the reason I've never done more than fifty miles on the fixie.

I ran 46 cm Salsa Bell Lap drops on my last touring bike (stolen). I reincarnated it with the same frame but went with 20 degree swept upright bars with Ergons and bar ends. Less than a hundred miles so far but luv-luv-luuuuuv it. It's going to take some tweaking, but you can often tell on an eight mile ride if something's going to work out over seventy, and this setup is definitely that.
