I definitely prefer the compactness of roll gear when travelling, and I also like the rapid-fire possibility when the scene is rapidly changing or if I simply think I will need to take several exposures. But... yeah, I'd rather have a croppable sheet of film in my hands when I go to the enlarger. I had a 612 back until recently (sold it) and it wasn't seeing much use. It was very nice but it was just collecting dust. However, there is a *big* difference in overall equipment volume when you go to 617. For 617 and 624, the case for a roll back is a bit better than for 612, I think. I am doing 4x10 now and like it a lot, though I am occasionally tempted to buy a 617 or 624 back to put on there. I do hope that some logic will persuade me otherwise!

Long live sheet film...
