The Royal Coachman was created in 1874 by John Hailey. But it was named by L.C Orvis, the brother of Orvis founder. It's not just a very popular brook trout dry, also landing rainbow, cutthroats, and browns. With peacock herl and red floss not really imitating anything trout just love it. My favorite way to use this pattern is the double dry setup as the Royal Coachman as the attractor and Adams Parachute as the second. It can also be used by itself. Depending on the size of the fly 5x all the way to 7X tapered leader and tippet are good choices.
