I have used some of this on training exercises, and it seems to work fine. Plain wire fishing leaders work great too, get at least 30lb test. And remember, it takes A LOT of snares, the sucess ratio can be as high as 20 to 1, you have to set out 20 snares, in runs, trails, front of dens ect to catch one animal. The exception is the squirrel pole. I have seen one of these take 4 squirrel in less than an hour
