I have encountered many fly tiers that have an aversion to materials that are not natural. Both in the United Kingdom and United States, I have heard fly tier?s say: ?Well, Bergman didn?t have any of that?, or ?Halford would never have used something like that!?, and so on and so forth.
I don’t think I’m an elitest but while the substitution of material for stuff no longer available seems perfectly logical, I am repulsed by using things like wobble lips, jiggling eyeballs and rattles. Worse yet is that they still call them flies and not lures.
