Thank you Ian. Yes, that was what I was talking about. My wording wasn't very clear in the original post because I was confused, since it appears I misunderstood what I read. What I read was that it didn't really make any difference which developer you used. But they were referring to which PAPER developer, not which film developer. I thought that they meant film developers, and couldn't understand why one developer that was drastically different different than the other, and D76 vs Rodinal is a good example, wouldn't result in prints that were different from each other. Even after assuming that the printing process sorta equalizes things.
It's possibly a given that if you're printing on RC papers then your developer choices are not so important, but of course w/ fiber it might be, especially if you were toning the papers.
