One of our favorite flies that we just can't be without. On slow days we've seen this bug do the trick. The pheasant tail fibers poking through the wire makes this bug look as realistic as they come. Add a few hot spots and you've got a killer combination.
Fished year around from wild streams to tailwaters. Sizes #14 to #18 work great, with our favorite size being a #16. If you need teeny tiny, then a standard zebra would be our recommendation.
