No. 88 Weighted Nymphs #12 Barbed, 9 flies per pack. These are often effective when the fish aren't responding to flies on the surface; try letting them sink a bit. If the weight is too heavy, you'll get snagged frequently, and the movement in the water becomes unnatural. So, I've placed small beads on the sides of the flies, making them easy to use in my main fishing grounds, the headwaters. There are three body patterns: yellow, brown, and peacock, with three of each color. The tails have a UV color accent. This is one of my main flies that I've used and loved for many years.
