One of the best grayling lures I've found. They are heavy for their size, and tumble along rocky stream beds very well, sort of rolling along. They don't get hung up as often as spoons, and having the treble is nice for hard fighting fish in a current.
I've also used "Lil Jake" lures when I couldn't find Super Dupers. Same idea. They seem even heavier for size, which I like.
http://www.basspro.com/Jakes-Lil-Jake-Lure/product/80083/I once read that they are supposed to twist your line in one direction, and when it gets too twisted, it will start turning the other way to untwist the line. This is why they don't have built in swivels. Can't say I've seen that happen, they seem to twist my line like crazy, but that comes with river fishing.
Edit - Jake's are Made in USA!
