Funny thing is, I actually usually use 943 OMNIs with my head as a biaural baffle when stealthing nowadays (which I don't do often but when I do, or when I want to create biaural ambient recordings). Anyway, I've actually found that despite the added ambient (talking, etc.), if I can get myself into the sweet spot, I prefer the omnis to even cards, plus they are much more forgiving when it comes to head movement, lol. But YMMV of course.
