The Bead Head Prince Caddis Nymph is well known for fishing steelhead trout and whitefish. This is a great dropper fly pattern underneath a large caddis dry fly or other searching dry flies. It's also great for euro nymph rigs too. It comes with a tungsten bead to get you down to the right water column quickly for those short drifts.
A small hook that can catch some very large fish. Zinger Fishing is a big fan of this fly pattern!
