fish4trout,
I don't know the OP (as you put it) and don't know the other posters. The OP has had 51 posts so maybe he has a feel for the types of responses. Personally, when I read John Scott's post I thought that he was basically expressing the humorous fact that no one really knows. So, to the OP, try it. Let us know when, under what conditions(water, weather, sun/overcast, etc.), how'd it do, etc., and maybe, just maybe you'll know if, when and why that fly pattern works.
Okay, to comment on the fly itself:
- Hook looks and is described as much too heavy to use for a dry fly, although that seems to be what's tyed.
- Wings look as if they will 'helicopter' and destroy the tippet.
- Tail may not balance the hook bend.
- Body much too large in diameter.
Not that any of my comments matter one iota insofar as fish catching. I'm only giving my own and personal visual impression.
So that's my 'constructive criticism'.
