He also references tying a Green Drake (eastern) pattern using
fluorescent calf tail "forty years ago".


I still use fluorescent green calf tail on my Green Drake duns. Probably not
necessary, but it does enable visability in low light, and when greased, the
calf tail keeps a pretty heavy (they are tied on
#10 streamer hooks) dry fly afloat for a bit longer.
