I’ve got a question about one of the materials that is used for the classic version of this fly. Even though it’s relatively “new” a few different versions are appearing. I am asking about the spey style classic Dirk Wiggler. There is a material worked into the hackle that is something like rubber something like straw. It’s limber but not as limber as rubber and it’s stuff but not too stiff. I can’t figure out what it is. Any help is apprecieated.
