North champs I have to think 503 is a lock -- they're in a league of their own.
South champs is more of a toss-up. 3132 has a phenomenal program but would be the youngest member of the Hall of Fame by a significant margin, whereas 1311 and 1540 are quite a bit older but perhaps a bit less flashy and well-known.
(I'd prefer 1540, of course, but that's just me

)
