MB 550's for me. Haven't lost a single coyote in one.
I'll have around 50 of them out during trapping season along with my old Victor 3-N's. I have base-plated my 3-N's to mimic the 550's center axis and almost totally eliminated any foot damage. I have quit rebuilding my 3-N's, choosing to replace them with 550's.
@ihookem, the only real reason to wax is to stop any further rusting and to slightly lubricate them. Nothing to do with scent control.
IME, human scent disperses pretty quickly. That doesn't mean you should handle them with bare, sweaty hands.
