+1 for All City Big Block, I was in similar boat sans snow & ice but wanted something with bigger tire clearance I could take into the dirt so true track frames wouldn't cut it (although All City's Thunderdome is indeed sexy as hell), figured if the "FG gravel" experiment didn't work then I'd still come out w a killer bike for pavement.
After a few months riding 80% gravel I can declare said experiment a success - takes anything I can throw at it (stuff I would not have been confident doing on my old Peugeot FG-conversion), quick and responsive but doesn't feel overly stiff, and the geometry has been perfect for my usual rides in the ~20mi range.
Have posted elsewhere but for the hell of it, this is the current state (will replace Zipp stem with Ride Farr "Headspace" stem whenever it gets here from Australia):
