Around here the biggest macro thing would be finding the right log in my opinion. The set itself can be awful effective BUT finding the right one seems to take some time. About 1 out of 50 really shine and when I see that one and its readily accessible then setting it up can be worth the effort. But I dont go out of my way looking for one to set as the other 49 tend to amount to squirrel crossings and there's usually a better set that's more easily accessible---as in not many steps from the truck. I dont have more than a couple of 150 sized traps. For me its either 120's or single spring 160's when not under water
Found the same scenario true in my part of Michigan. In fact I setup cameras on a couple, what I thought were good cross-over logs a few years ago because of nearby mink sign. I videoed a couple of mink using the logs through the length of that summer BUT more mink were seen going under the logs. Every frigin small animal you could think of though was using the logs way, way more often than mink!
I did find a particular log that cats & coyote wanted to use while otter trapping. This log, about 8” dia and 15’ long was laying parallel to the creek about 20’ off it. This log was just above a frozen wet spot, I mean I couldn’t slide my boot under it. One day there would be a cat track on it, 3 days later there mightn be a coyote track, and three days later maybe another cat track or coyote track all traveling in the same direction not a single animal stepped off onto the ice less than a foot below the top of the log.
