Beadhead Hare's Ear
Note: I don't fish many nymphs, but those that do I like to keep simple and "disposable". These fit the bill nicely, as Jan Simon's dubbing brushes make the task of creating a spikey/sparkly body a snap. These flies can be knocked off a couple dozen or more an hour, which certainly helps me fish them more effectively as I'm not afraid to fish them right along the bottom.
