I am also curious about the format but there is one more point that wasn't covered yet I think. There is of course the possibility of using half-darkslide with 5x7 - have tried that already, it's fine, BUT - if your aim si to travel or hike longer distances it is good to have a camera smaller than 5x7 AND mostly having the convenience of a roll film back and not lugging film holders. Imagine a multi-days trekking - how much space (and strength) you'd need for appropriate amount of filmholders (or changing tent) - and compare it with a couple of bricks of 120 rollfilm. Huge difference to me.
(In a similar line of thought I am now lusting for a backpackable 4x5 to be able to shoot 6x12 rollfilm negatives while hiking.)
