Wing, I do use coon cuffs--they are a dog resistant trap.Cage traps work weel on coon ,but I would hate to haul a bunch of them on a fur -trapline.
The cuffs work well for me and are not big and bulky or visible like a cage trap.
Your snares have to be set in trails the animals are using.Look for spots in the trails that are necked down,place your snares there.
Good luck, Tom
