I mostly agree with what you said. I used to use the scent loc clothes, use a doe in heat drag line (using the "hot" lure that year), rattled, grunted, bleated, set mock scrape lines, and tried the latest sure thing, off the wall tactic I read about in the bowhunting magazines. I still use scent killer spray and the fresh earth scent wafers but have gotten away from grunting so much and don't use hardly any scents anymore. I will use the grunt call when I get into my stand and that is about it for calling. Sometimes I will use some trails end placed on the trail where I want them to stop for a shot.
