Chuck,
Correct. Again, as I said in my original post, I think what is so confusing to most is their familiarity with "Turkey Biot Quills"..........these being the feathers and fibers so many tie segmented body flies with - whether "fuzzy" or smooth..........
Make sense?
A web definition of a Biot Quill feather:
A biot is simply a single fiber from the leading, or front, edge of a primary (first row) wing feather. On the feather, the biots lay against each other, leaning toward the tip of the wing. This allows air to pass over them and flow against the fibers on the rear side of the feather, which are longer, narrower, and more delicate, providing lift for flight. This is similar to an airplane's wing... wide, blunt in front, tapering toward the rear. It is easy to tell the biots apart from the rear fibers, as they are shorter, stiffer, and lay closer to the quill stem.
Here is a Turkey BIOT Quill:
