Having logged a lot of miles with both Campagnolo and Mafac brakes, I'd say either works fine. I think the pad/rim combo is a larger variable in terms of stopping effort but you'll maybe see a little more braking torque from the M brakes than the C for a given lever pull force, but the C brakes will be less prone to squealing. I would add that the last gen script logo Record C brakes seemed to me to have required even less of a tug on the levers than Racers but with different pads or rims, who knows? I am a fan of the eccentric cam Campagnolo caliper QR that will hold whatever adjustment you make and I like having the adjuster barrel on the caliper too so minor points to the C brakes for those.

I don't get the whole Campagnolo "speed attenuators" sobriquet, I can lock either wheel with a two finger pull with them given fresh pads and clean braking surfaces on the rims.

(a lister graciously gave me a pair for shipping cost some time ago.) since it will be a commuter specifically for winter in California, i may want to put on newer brake blocks if it really makes a difference. but i seem to remember last time i had a bike set up with old mafacs and orignial pads (late 70s- early 80s) that they were pretty decent in the rain on aluminum rims. if some of ya'll still have them, will you venture an opinion?
