For those of you who are having difficulty catching these things (assuming they are present), you might try a beadhead prince nymph. When I lived up north, I gave up on the prince because I got tired of fighting my way through the whities to get to the trout whenever I fished it. Luckily, I live just south of Dub's whitefish heaven, so I don't have to worry about them any more, although I do catch a few on the trips north and try to get pictures to show to REE, knowing how much he likes the things.
