According to theory, the first parts of a drifting upwinged fly seen by a trout, as it nears the compass of the trout's window, are the wing tips, then the lengthening wing, down to the thorax, by which time salmo trutta is ready to tip his nose up, rise, intercept the fly and swim back to his 'on-the-fin' lie.
Said trout will also see the footprint of the fly, as little lights on the surface, beyond the perimeter of the window. So, the angler has a choice, it seems to me -- go for wings, double-split or sight-post, or opt for the footprint approach. You should get both in one with a winged dry fly.
Sadly, double-split-wing dry flies often have opaque wings, not very natural, easily messed up by the trout, and add no buoyncy to the fly; but production of good ones is the hallmark of the expert fly tyer, so they used to say. a ppersonal choice is the plain, hackled dry-- simple to tie, fair flotation and fairly robust.
If the fish are taking small stoneflies, or hawthorns, there won't be a lot of wing on show, as the wings are stacked or folded flat, respectively. You fish what you want to fish!! TC
PS you could try fishing the fastest water in which you can keep in contact with your fly. In the turbulence, you occasionally get away with murder!! It's why some of us fish fast little streams.
