I think this is a very subjective question. From a cultural, geographical and industry-specific standpoint. A natural shoulder suit for a creative executive in the US would be more than appropriate, as suits are rarely worn and no one will pick up on details as the suit itself establishes enough credibility. In contrast, a British or Swiss financier's suit might ruffle feathers in a board room if it doesn't adhere to the sharp-lined, masculine "power suit" aesthetic.
In consulting I feel a natural shoulder makes for a nice balance between the formality of a suit, but the approachability of a more casual/natural drape. Then again I'm pretty sure no one thinks about this detail nearly as much as I do...
What say ye? Sorry I don't have pics for examples at the moment... but what do you think? I'm not saying no shoulder padding at all, but a very very thing/light padding and little to no roping.
I doubt anyone will notice apart from a very few who have form views on such matters. These days most people accept RTW and have no knowledge with which to question it. In any event the contract between the military styles of some Savile Row tailors and that of others such as Andersons never excites any interest.
Your market research then should be put aside and you should concentrate on the product
