of those three, use the cordura. Its often nice to have two sheaths for the same knife. That way, you can keep one strapped to your pack and one for EDC, or some similar arrangement. I'm in the same boat with my Dumpster Mutt, I'm waiting on a kydex sheath from the SY shop. In the meantime I'm using the sheath for my SOG seal pup (minus the liner).
