I am very new to fly tying, and I figured I would start out tying some nymphs that work well on my home water, the Gunpowder, in Maryland...pheasant tails and hares ear. I got a video with my kit and the guy tied in some lead wire. I was a little surprised, but not sure if it was common. I looked on youtube and found a good video, and he didn't use lead. What do most of you do? No weight, some with weight some without?
