A classic pattern, the Fly Formerly Known as Prince imitates many natural nymphs, and its beadhead gives it just enough weight to let you get it down deeper than a regular nymph. Swing this fly in riffles or runs to imitate many different types of mayflies, or fish it to prospect for trout. A great nymph with a touch of flash to attract trout, it's a must-have nymph for any fly box.

Sizes: 12, 14, 16, 18.
