Other than that, one consideration when choosing a canti is wide- vs. low-profile. Many people prefer low profile in the rear because of heel clearance. Long wheelbase frames (like mine) can tolerate wide-profile cantis on the rear, but a lot of modern bikes can't.
Otherwise, the only other major consideration is you want a set that take threaded pads. The CR720's by Tektro mentioned are pretty good, I have them.
the post mounts for the miyata fork are set closer to the rim than what you can find on modern CX and touring bikes, so those thinlines could be the key.
