My Bianchi sounds very similar to yours, Charles. Yes, the Campag. derailleurs and pedals are still going great. Don't be too hard on Japanese parts, however -- I still use the original SunTour downtube shift levers from my 1970 Nishiki Competition, and a friend recently put the matching SunTour VGT-Luxe rear derailleur on his daughter's bike, after she tacoed her Shimano. It apparently works fine with the Shimano 7-speed indexed shifter and freehub.
As for the Masi project, there is nothing wrong with either a Masi frame or a Brooks Pro saddle!
Incidentally, I regeared my Bianchi 50-42 / 13-15-17-19-21-23-26, which the Campag. NR derailleurs handle with aplomb.
