It's been thirty years since anyone fished for springers on the lower Snake (legally), so I can't tell you much there, but a little farther up on the Clearwater, k-14's have been the ticket....chrome with a chartreuse tail. Also have seen solid orange mag warts catching fish. Not that the k-15 and 16's wouldn't work, but you've got to remember that most of us are a bunch of steelheaders and the 16's are a little bigger than we are used to. Last time I looked White's outdoors in Spokane had herring. goodluck
