bountyhunter,
I've used small jigs rigged under a pencil bobber that moved by wind ripples on the water. They worked OK but I never had a fish hook itself hitting the jig, still had to set the hook. Maybe something like a Rapala set in fast moving water would work, don't know, never tried it.
Years ago I read somewhere that in pilot (military?) survival kits the fishing equipment included white feather jigs because they were the closest thing to a universal lure. FWIW
