All of my experience with Foma films was in 8x10 sheet format. Got a few very nice prints, but the dicey quality control and other idiosyncrasies just didn't make the lower price actually worth the risk, or the lack of versatility compared to what films like TMY and FP4 consistently deliver. A lot of effort goes into it up front, so I need both my gear and film itself to be as reliable and predictable as possible. Whenever 8x10 film gets too expensive for me, I'd rather shoot my favorite films in 4x5 rather than something squirrelly in 8x10.
