Want a fly that will catch fish? This is the one. It was developed on the San Juan River in New Mexico but it has found its way to be fished all over the world. What fish can resist a worm? I always carry at least 6 of these bad boys in my box in multiple colors. It is irresistible to many fish such as trout, bass and pan fish. When you don't know what to fish tie one of this on as a top nymph or a bottom nymph. Now's your chance to fill your fly box with this staple fly. All of our flies are tied on chemically sharpened hooks and made with premium materials. You won't be disappointed with the quality!
