Mark, those are very similar to some flies that I tied for use on bass and pickerel. Mine are super hair and krystal flash tied on a bass bug hook so that the wing material covers the point of the hook and the fly rides point up. Then I dip the front part of the fly in softex (about half way to the hook point) so that the wing material acts as a weed guard. You can use a twist-tie or a piece of thread around the wing material and the hook point to hold the material in place while the softex dries. They work! I've caught bass, pickerel, perch, sunfish and rock bass on my version.
