I do not know if I would get some or not. My gut says "YES," because I used to use Plus-X in sheets. However, it was a different emulsion, I have now got myself adjusted to FP4+, and I don't shoot all that much 4x5, like I used to. So, I'd probably buy a few boxes just for the heck of it, if it was priced similarly to FP4+, but I would not buy a sizable quantity.
If it was a clone of the old Plus-X sheet emulsion, then I would probably want to buy at least 250 sheets of it.
