Pheasant Tail Jig Nymph - Copper Black Special. Pheasant Tail Nymph (PTN) is one of the most universal nymphing pattern 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 too many snags. Tungsten bead will get your fly quickly to the bottom where fish are feeding. Copper in combination with black works great on grayling and trout.
