This is a very informative thread and nice to see so much discussion with the intent to share knowledge and help out.
I like some of the suggestions, but what I have been doing is simply making test strips and notes. Even though I do make some notes, it seems to resonate that I'm going to start from scratch regardless. But at least they give me some data that I would not otherwise have to begin the process again.
I also feel that one can become somewhat accustom to a particular paper, I for instance find the new Art 300 somewhat slower than Ilford's regular fibre paper. I also like their warm-tone and really like Ilfobrom Galerie. And then there is the toning to consider, but that's another thread I suppose.
