The handling is good, ride isnt squishy but not crazy stiff either. I've always been told that Boston streets are crazy bad so based on THAT I'd probably rock 28c's!
Easily. I normally ride 32s, and the frames and fenders I'm looking at will handle up to 38s. Smallest I've ever ridden for any significant amount of time was 28s (with 25 front and 28 rear briefly before that), but that was a couple years ago.
Edit, just for the record: freewheel single, not fixed.
