Another thing you can do with the wing is use schlappen. G.P. breast feather, dyed G.P. tippet, dyed Amhearst tippet, or dyed G.P. saddle feather strands instead of hair for the underwing. This way your wing would be composed of the peacock sword, the dyed feather strands, and then the bronze mallard over. This would make for a more mobile and even more attractive wing.
You should post the fly with the changes so that everyone can see what these material and hackle placement changes do to the overall look of the fly and why I asked if you had thought of tying it with those materials.
