The CDC Formerly Known As Prince is the Prince attractor nymph tied with CDC, over a peacock body with shiny biot wings. The CDC adds lifelike movement and a soft profile that makes the fly deadly in the surface film, where trout feed on emerging caddis. One of the most productive nymphs day in, day out, it suggests caddis and a range of other naturals. Available in #12, #14, #16, and #18, it covers bigger water down to small flies for selective fish. Fish it dead-drifted under an indicator or as a dropper behind a dry — a go-to attractor nymph for trout water everywhere.
