Nope on decoy. Or bait for that matter. My favorite setup? I suppose that I don't have one really. I prefer to still hunt if the terrain allows. Spot and stalk is also a favorite, but I've been known to rove while deer and hog hunting or, if noise while moving is an issue, I'll set up near water/food sources or a natural funnel and ambush them.

Make em sharp and shoot em straight, or leave em home.
