The Hanak RS+ tungsten jig head directly correlates diameter and weight, and comes in a copper finish. Copper naturally complements brown, red, and pheasant-colored bodies with a warmer tone than gold. 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.
