I looked at some pictures and thought the turnback cuffs aren't actually that noticable, I guess it depends on how I have it down but I thought it is mildly subtle.
I wasn't planning to get it extremely roped, just so the shoulder has a clean line, which I prefer, and I think I want it on most my suits not just my DB anyway so I don't think it's a huge deal. I'll talk to the tailor and see if I can try turned back cuffs and have it removed if I don't like it first. Either way I'll post some pictures when I do get them so you can be the judge of it.
As for loudness I think my age and general context in which I wear it does allow me a bit of flexibility. I don't really work in a conservative enviroment so it'll get more wear than most people I think.
