When I use to do a lot of river fishing I would use a very simple streamer made out of dark red and brown deer tail tampered at the eye with about 15 strans of hair. Used them on a # 6 or 8 long shank hook. It looked like a night crawler going down stream. Caught a many eyes on it. An ole timer taught me how to fish it when I first started to fly fish. He never use anything but a fly rod for all his fishing.
