The Copper Body/Black Rubber Legged Copper John is a super effective pattern that has taken the fly fishing world by storm. This fly sinks quickly and is a great choice for deep nymphing or as a dropper off of your favorite attractor dry fly. Fish seem unable to resist the combination of color, flash, and realistic shape this fly offers. The addition of rubber legs creates added movement which makes this fly hugely successful. Most guides and serious anglers never enter the river without having several variations of this productive pattern.
