The Prince Roo is my variation of the Prince Nymph. Tied with a synthetic peacock curl, Prince Roo outlasts and is more durable. Imitating an abundance of aquatic insects including the stonefly.  It also makes an excellent attractor or anchor on a double dropper setup. My favorite way to fish The Prince Roo is the double dropper setup under an indicator with either the Flash Scud, Roo's Eggstasy, or Hoot's River Juan. It works great by itself with or without an indicator bouncing off the bottom. 5X to 6x tip it is an excellent choice with Hoots furled leader. In some cases you may have to add pinch weight.
