Tungsten nymphs are arguably the most favoured river fly pattern. They are nymphs where the usual brass beads are replaced with tungsten beads in all shapes, sizes and colours. Tungsten nymphs reach the fish in the strongest river stream and deepest pools. Black Tungsten beads are the most popular while coloured beads are also very useful. Large oversize beads are often tied in the middle of the hook these will drift with the hook up, this will lessen the chances of snagging the bottom of the river. Some times an unweighted nymph is attached with 12 to 15 inches of tippet and this nymph will bob up and down a few inches clear of the bottom.
