IF I were only going to shoot panos, I'd buy a Fuji 617 and be done with it. But I'm not ever going to shoot only panos. I see in more aspect ratios than that. A failing, what can I say?

An alternative to traditional cut film holders is Fuji quickloads. Quickloads save a good bit of weight over traditional film holders. And presumably over roll film backs (I haven't done any weight comparisons myself as I decided against a roll film back and don't have one to weigh).
