Its been years but we caught a few back in the 90s with number 3 Northwoods when bobcat trapping coming into cubbies with beaver. If I went for them I'd use a 750 with a 3/8 OS and double lamination. Wouldn't go anywhere. If not a 750 I'd use a 3/32" or 5/64"x 12' snare with a high anchor and double swivels in a good entanglement area. Don't really think they would be much higher off the ground than my lynx snares either. Id set bottom of the snare 14" off the ground with an 10-12" loop. All dreams I guess lol.
