Pheasant-tail nymphs have always been a first-rate fly for imitating small mayfly and stonefly nymphs. The naturally segmented look of the pheasant tail along with the right texture makes these flies super-realistic. Adding a bead-head to this time-tested pattern only improved its success rate. It now sinks faster to get down to the bottom where the trout are and the glitter from the brass bead also aids in attracting a hungry trout's attention. Per 3. Sizes: 12, 14, 16, 18, 20.
