In another sequel of my series "At The Vice" I prepared a fly tying procedure of my favorite river nymph - original hybrid forms of Pheasant Tail (PTN) and March Brown nymphs tied on a loaded hook with a lead drop by Jiří Klíma! I really like this kind of nymph because of its natural look and great versatility throughout the whole fishing season! Very effective pattern for native river brown trout, rainbow but also larger chub and grayling. Also applicable on natural trout still waters! AR Drop Thorax March Brown PTN - as always in Step By Step fly tying gallery with  description of used fly tying materials!
