NYMPH HEAD "EVOLUTION" FLY TYING BEADS - The future of fly tying is here! The next generation of modern tungsten fly tying beads enabling anglers to create fast-sinking, more realistic looking nymph patterns with more anatomically correct head profile, natural color and size proportion relative to the insect's body. NYMPH HEAD EVOLUTION is a family of tungsten fly-tying beads molded in the shape, size and natural color of the heads of the three most common aquatic insects that trout feed upon and which fly fishers attempt to imitate, namely mayflies, stoneflies and caddis flies.
