4"x20" would be close to the ratio I'm talking about. 2.25 x9.75-10". But again, using darkslides adds weight with more film holders. I think a single rollfilm holder would be much less weight: a selling point for backpackers. Then again, if money is no object, they could buy the 6x24 camera that weighs significantly less. I can't.
