I hear ya' Steve. I can handle a 42 small ring in my new locale, but the biggest climb is about 50 feet. In my old stomping grounds of Montana, I ran a 46/29 double (TA cyclotourist) with a off-topic 13-29 10 speed Campy cluster on my KOF "go fast" bike. For period correct, wide range drivetrains though, my personal favorite is a half-step with granny (46/42/26) paired with a 13-30 6 speed freewheel. This gives me the same number of distinct gears as your standard modern triple with a 9 or 10 speed cassette. If it were me, I'd leave the Colnago and Trek the way they are, and build up that Fuji with SunTour Cyclone GT derailleurs, SunTour 13-30 freewheel, and to keep the Japanese theme, a Sugino AT or similar crank set up in half-step plus granny configuration. I'd also throw on a pair of SunTour BarCon's just cause I really like 'em. Good luck!
