Bob, I was indeed inspired by your Campified Continental. I gave some thought to putting some early 60s Campy Gran Sports front and rear derailleurs on, but I do like the look of the Shimano 600. I took the bike for a longer ride today, and those mechs worked perfectly. The Campy crank is a "traditional" 52/42-tooth setup.
And glad to hear you're enjoying riding on the Cape. I've lived in the Boston area for 15 years and have yet to go there! Someday, hopefully.
