Swimming ISO Nymph

Swimming ISO Nymph

The Swimming ISO Nymph was developed as a versatile Isonychia pattern. With the Brass FlyColor™ Bead and the Daiichi Swimming Nymph Hook, the fly can be used as a nymph on the bottom with split shot, as an emerging or active nymph on the swing, or as a dropper below a dry. The copper bead, copper-brown wire, and the dyed peacock were used for extra flash. The copper colors are effective in waters with high levels of tannic acids found in Northern New York where I am from, such as the Ausable, West Canada Creek, and the Black River.
