When I got started, it didn't take me long to figure out I was catching 90% of my coyotes in 10% of my sets. I realized it was specific location types that produced the best. I will use a few double sets in key locations and move on. I've tried it both ways and this approach has proven time and time again to produce more coyotes with much less work. Obviously, there are many ways to set up a coyote line, this is just what produces best for me. I'm enjoying your posts and good luck.
