Older double FDs usually had a 14t capacity, which is pretty conservative. They work fine with a compact, they just seem to be a little less precise than a 53/39. .FSA and Campy has made compact specific FDs for a while now, and new 6700(and I assume DA and 105 too) FDs are 16t capacity, so its moot anyways.
