FWIW, here's my simple, easy answer (copied below from a post I made on another board): TRP CX8.4 or CX9. They are designed to work with brifters -- no Travel Agents or any of that stuff. I use v-brake (flat bar) levers, but others I know -- including LBS wrench, who races 'cross -- have put them on 'cross bikes (brifters) with excellent results.

I use the CX9s (replaced the generic Tektro mini-vs on my bike). They are, quite simply, superb. Provided you use good cables, they go into -- and stay in -- adjustment like no other v-brake I've had (junk Promax, generic Tektro, various Avids). They've been on my bike (only bike; 3-season daily commuting, weekend distance rides) for a year and a bit -- not a single adjustment needed other than a bit of cable tension to take up pad wear. Stopping power/modulation as good as it gets, in my view. They are sold in boxed sets (f/r) with extra differently-angled noodles to allow for different cable runs. I was horrified by the price, but wanted 'em ... worth every dollar if you like powerful, easily-modulated, reliable brakes.
I think Germanicus is right about CX8.4>SRAM, CX9>Shimano road brifters, though you might want to check.
