Pheasant Tail Jig Nymph - Copper Special. Pheasant Tail Nymph (PTN) is one of the most universal nymphing patterns and has it's place in every fly box. This is a custom made PTN tied on a high quality jig hook. Nymphs tied on jig hooks ride "upside down" and therefore allow to fish the bottom of the river without getting to many snags. Tungsten bead will get your fly quickly to the bottom where fish are feeding.
