The Hanak RS+ tungsten bead directly correlates diameter and weight, and comes in gold. Gold remains the classic choice for traditional nymphs and brown, tan, or olive bodies. The tapered slot makes it easy to tie onto jig hooks and helps concentrate up to 10% more weight around the hook. Sizes range from 2.30 to 4.60 mm and from 0.09 to 0.80 g; packaging: 20 and 10 pieces per bag, depending on the diameter. Compare weights rather than just diameters: it is the actual weight that will determine how the nymph behaves in the current.
