Cast the Soft Hackle beadhead Pearl Nymph across the river with a weight above, let it drift and sink, then let it swing downstream, which lifts the fly upwards in the water. If a fish doesn't grab the fly on the dead drift, they will often take it as a rising caddis. The soft hackle bead head pearl fly is an effective lake pattern also, imitating a rising callibaetis nymph, or just as a buggy looking meal. Yum, Yum!!
