Take a beadhead Pheasant Tail and give it a heavier bead, and you have a faster sink rate, and slightly different action to foll even the wariest of fish.One of the top five trout nymphs ever tied on a tippet.A near perfect imitation of the blue wing olive nymph, also works great for a general mayfly nymph attractor.Great sink rate, classic silhouette, and that peacock thorax, one of the best materials ever wrapped on a hook.The beadhead allows the nymph to sink quickly, 'swim' attractively, and appears to be a tiny bubble many nymphs rise on.A must have for any trout angler.
