I asked this question while contemplating buying some because Iford's MGIV FB (that I usually buy) is more expensive at $82/100 versus Oriental's $68/100. I find it hard to believe that no one ever used this paper with selenium to provide feedback, but anything is possible I guess.
I've baught some and used it this weekend and my own feedback is very good. It tones with selenium to my liking, about the same as MGIV. At $14 difference per box, I believe I can make a switch without any real difference that I can discern.
FWIW
