No. 83 Weighted Fly #12 Barbless, 9 flies per pack. When surface presentations aren't producing, try letting these sink a bit. Often, that's all it takes. If the weight is too heavy, you'll snag frequently and the fly's action will be unnatural. I've placed small beads on the sides of the fly to make them easy to use in my main fishing grounds, the headwaters. This is one of my main flies that I've used and loved for many years.
