The Hanak Classic brass bead puts less strain on the rig than a tungsten bead of comparable diameter, in silver. Silver pairs particularly well with gray, black, white, or pearlescent bodies and gives a cooler look than gold. Brass provides a more moderate weight than tungsten of a comparable diameter. 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 profile and the desired sinking rate, then check how the bead moves along the curve.
