Phil always put together great step-by-step tutorials and goes the extra mile to provide information about the fly and materials used. This pattern was born in the vise of fly tyer Trevor Nowak and uses a big helping of Rhea tendrils to impart action into the streamer. Rhea has become quite popular in steelhead and salmon flies over the past decade thanks in no small part to tyers like Nowak rhea guru Todd Scharf. Phil has some extras in the article about preparing the feathers to use in patterns so the herls are wrapped and paltered easily.
You can find the full step-by-step tutorial on Phil’s website http://flycraftangling.com, and get some insights to tying with rhea.
