I've got 3 Duke #2 coil spring traps
Years ago in Northern MN I saw a good sized wolf being held by a 4coil #2. Every so often it seems you get one that doesn’t fight the trap much. Most do however.
I think an MB 650 with inside lams would be my minimum, a 750 would be better. They get caught here as incidentals and those traps hold the biggest of them.
Depending on any sort of restrictions on snares in Idaho, they would be a bit more suited for the job.
