I've got two Kata bags, but I no longer use either of them. They are extremely well-made, very tough, but seem to be designed for equipment that may be more delicate than cameras -- that is, they are over-padded, unless you're actually *throwing* your bag around. If I was always shipping my equipment from one place to another, with baggage handlers, then I might well go with a Kata, because they *will* protect the gear; but for carrying, it's overkill. The extra padding, and the fact that they are apparently designed for very active uses that requires a slimline bag that sits tight to the body (military?,) means that they will not carry nearly as much gear as other bags of the same size. There's a tendency to think "I need the toughest, sturdiest bag I can lay my hands on," but you've got to ask yourself, "Really?" -- because there are costs involved. I'm a pretty active guy, and my bags get beat around a bit, and I've gone to Think Tank. It's quite good, works well for me, and is more practical, I think. (Not that it's perfect.)
