Did some digging and found this thread. I want to use a Beseler Dichro head (23cIII) for Ilford and Kodak VC paper.

I found this on Ilford's site. From what I can see, I can choose "single" (Y or M) or "dual" (Y and M) filtration. Both will accomplish the necessary contrast change, but "dual" will have the benefit of making exposure settings closer to constant when changing contrast setting.

Do I understand this correctly?

Any suggestions for Kodak paper? If not, I'll just try the Ilford settings and see where that takes me.
