We could also have the jounin and chunin spam shadow clones (if they are good enough imitations to be indistinguishable by tracks) to make false tracks showing variously that we've left the swamp, we never entered the swamp and the swamp is an obvious fake to bait in any hunters, we've turned around and are hidden in some random mountain range, we've done X and Y other plausible evasive maneuver, etc. But more tracks = more Konoha risk, Konoha risk = we lack the info to evaluate.
That seems like a good idea. It might be possible to make the fake tracks too hard to spot by anyone not as good as Zabuza? Depends on our Jounins specialties, i guess.
