These lures a very difficult to find and are well worth the money. I use them exclusively for back trolling and anchor trolling for large salmon in rivers. I use kwikfish, flatfish, and maglips, but the stingfish consistantly out fishes all the above with its e chip. They are best suited for use in the mouths of tributaries when the fish are fairly aggressive. I've found that combining them with the use of braid line and 20-30# flourocarbon leaders produces the most hook ups. You can also use them late in the year for steelhead but the smaller sizes seem to work better for them.
