The royal wulff doesn't look like anything natural, but it has accounted for a lot of fish over the years. It works great in fast turbulant water especially if you apply a little floatant. One ofÿthe best attributes of this fly is that it is highly visible even for those of us whose eyes don't work quite as well as they once did! Out standing pattern for brooktrout and landlock salmon. Sizes 10, 12, 14.
