So I recently started tying PMXs. Obviously I needed new sources of aggravation in my life. After a few botches, I started to get kind of comfortable with the procedure, so I decided I'd try supersizing one into a salmonfly pattern. I used a size 4 nymph/dry fly hook, orange poly for the abdomen, then everything else was pretty much the same. The fly actually looked great when it was done. My best PMX yet, but when I gave it the bowl-of-water test, it floated at first, then sank like a stone after I picked it up and put it back in. I'm wondering if I used a bad portion of elk hair for the wing. I have not done much at all with deer or elk, so I wouldn't know the dos and don'ts yet. My elk patch has a lot of the blond-colored hair, but the longer hair behind (or underneath) it is very dark, almost black. I used a lot of this on my salmonfly wing, as I thought it would better match the natural's wing color. When it sank, I started thinking maybe this darker hair was more of an undercoat on the animal that didn't shed water as effectively as the outer, blond stuff. Am I on the right track? What other things could be sinking this fly? Or is this common, and floatant would take care of it?
