Have you ever experienced a situation where you have been told about a style of fly, you tied up a few , working slightly blind as you have never seen any. You interpet the information you have been given, the fly takes shape at the vice and as you cut the thread after the final whip finish you gasp, sit back mouth agape and stare at the fly in wonder.
I experienced this quite recently when I was given a style by a very experienced and generous angler who rates this style as been extremely effective for some specific imitations and also works well on some patterns as a general imitation.
When I first looked at my first attempt on the vice it simply screamed back at me "deadly" - off course like all flys they are not a universal panacea and will only be effective when fished with skill and stealth.
This is one example of this style, and I believe was intended as a March Brown imitation but works well as a general pattern.
This seemingly simple style I believe ticks all the right boxes and I can find nothing in it that negates against it being a superb design for upstream fishing and nothing that would put a trout on guard.

Try tying a couple in this style, try a Greenwells with Waterhen coverts/undercoverts you wont be disappointed.
