No. 108 Weighted Nymph Flies #12 Barbless, 9 flies per pack. These are often effective when drifting just below the surface doesn't produce results. If the weight is too heavy, snags become frequent and the movement in the water becomes unnatural. Therefore, small beads are placed on the side of the fly, making them easy to use in my main fishing grounds, the headwaters. There are three body patterns: cream, brown, and peacock, with three of each color. UV color is added as a highlight on the tail. This is one of my main flies that I have used for many years.
