I agree. It will show the angles and form of the body better and be a lot easier to shoot in lower light levels.
While I really like the formality of the black jacket, it looks more like an old-fashioned naval uniform or a formal suit jacket. It is more intimidating.
Sometimes bodyguards need to be able to look like everybody else and blend in a little more than that. The bronze would look more contemporary, for clubbing or informal occasions, for looking like some minor official instead of The Muscle. It'd be much better for that Scarlet Pimpernel thing of looking, erm, ever-so-harmless.
