I'm with Chuck Schmidt on the pinnacle issue. I favor a bike with the last of the Super Record group. Mine would be (is) a Cinelli with Cinelli VIP bar/saddle combo. My only era cheat would be C-Record retrofriction shifters.
Failing that, an early C-Record bike with Cobaltos and retrofriction (like my Della Santa). For my part it's a very tough call as to which was/is tops.
