When I was in college I worked at the local sporting goods store. On a side note, I'm still looking for a new shop as it was blown away by a tornado nearly a year ago. I live in Joplin, MO where we got hit with an F5. Kind of sad to see my old employer that had been in business since the 50s just disappear.
Anyway, while I worked there I probably saw twice as many whisker buscuits come through the door than anything else. It's a proven rest, and the one I use. Only negative I can see (and this isn't to be dismissed) is a little noise. I've worried about it some when treestand hunting. I still probably won't change any time soon.
