What I could never understand if the dumb trout are biting a swivel often enough to be a concern why in the heck do anglers worry some much our chironomid patterns, size of those patterns or the depth at which we are fishing them. Why not just tie some dark non-descript pattern say 3/8 inches long and just let it hang within 3 feet of the bottom and start catching fish.
