The Rubber Leg Swimming Nymph is an excellent imitation, not just for nymphs but also for crawdads. I like to call them Mud Bugs. These are not just Trout favorites but also Small and Largemouth Bass favorites. With those Bard flashy legs and that buggy look, Trout and Bass cannot resist. You can use it like a streamer with Hoot's Furled Leader 3FT, 2ft of 5x -8LB. Can swing it also and dead drift it under an indicator with Hoot's Furled Leader 5FT, 5X or 6x.
