Going back through my journals, blind sets were my top producers (no bait or lure) but those sets that I did have baited or lured produced in this order: 1.) mink gland lure, 2.) red fox urine, 3.) bloody muskrat carcass and mink gland lure combo.
I did try some light skunk essence a couple of seasons awhile back, thinking heck they have a relatively similar genial background in the species. I honestly was not impressed with the results.
