Re: Pick-out dubbimg???
all the above, and pretty much any fly, except dry flies.
The dubbed bodies on nymphs etc simulate legs, and on emergers the stray fibers can help trap air bubbles like on the real thing. If you are tying a bunch of a particular pattern take two or three and pick out the dubbing ( i use a toothbrush with the bristles cut short). THat way you have the best of both worlds in your fly box
