Somewhere along the line, I procured a second set of Super Duke mirrors. Those are still on the 599. 599 mirrors are way ugly. There's no hope there.
All mirrors are kind of ugly, and stick out, IMHO. Like I said, if they're matte black, they're a lot less noticable. When I park my bikes for the winter, the bikes go in my basement. I'll take the mirrors off, if it's easy to do, because I think it looks cool. But when they hit the street, I put the mirrors back on. Safety first.
I did like my painted 919 stock mirrors.
