I'd go with Modolo as well, assuming Galli and Modolo are your only choices. Modolo calipers assemble differently than Campy and its variants though. I'd spend a little time tearing them down and putting them back together before mounting them on a frame. Also, Modolo Corsa are ubiquitous, but they are the very lowest end of the lineup. They work, but don't inspire confidence. The lever bodies are also plastic (maybe good for a weight weenie build). I'd look for something more upscale, like those Speedy's on
SurferRosa's Miyata.
