Asking "why" in regard to many materials used for fly-dressing, unless
they are used a a result of very specific properties is a bit
pointless. Often, the answer will be "because it was there".
Although I'm certain you are right about the most common answer,
I think that choice of materials is a key factor in all design, including
flies ....
