dual pivot brakes are overrated. good brake set up is more important. anyway, mafac center pulls were great, just make sure the bushings are brass, not plastic, and your set. they put out as much if not more power as a cantilever, so easily as much as a single pivot caliper. get some koolstop salmon pads for em...and roll. or if you cant source mafacs, but you can they are every where, diacompe makes some.
