You are missing my point! I said "results similar to" not "good results". In fact, some of these substitutes may be as good or better for tonality. You are the one to decide that, as I also said.

Although if it does not satisfy you, then it does not.

Generally, a modern film with the right "tone" will have higher speed at the same grain and sharpness or better grain and sharpness.

And I do know what you mean because after all, we had a motto oft repeated at EK, "We sell pictures, not curves".
