Fly Tying – Split Case Nymph

This pattern has become a standard for anyone that fishes the East Tennessee Tailwaters. We have very prolific Sulphur/PMD hatches that last half of the year. The original split case pattern, developed for western rivers has made it’s way over to East Tennessee, but it calls for biots pulled over foam which are usually not durable and difficult to tie with. We have tweeked the pattern over the last few years and this is the current version I’ll be using as sulphur season is just around the corner. I’ve been needing to get a head start on tying them up.
