The Hanak Classic Fluo brass bead puts less strain on the rig than a tungsten bead of comparable diameter, in orange. Orange pairs naturally with warm-colored thorax, orange tying threads, and hot-spot rigs. Brass ensures a more moderate sink rate, while the fluorescent finish creates a distinct splash of color. Sizes range from 2.00 to 4.70 mm and from 0.03 to 0.31 g; packaging: 20 pieces per bag. Choose the size based on the nymph’s silhouette and the desired sink rate, then check how the bead moves along the bend.
