I like to experiment with flies and change them a bit to see how they will work. So I do add bead heads to a lot of flies that do not normaly have one. I have found that a lot of them work as well if not better. There are no rules in fly tying except for some fly tying contest. You can add a bead head to most any wet fly. Try it some time I am sure you will like it. Just my 2 cents John
