From what I read about emulsions of Agfa, Kodak and Illford, they are all using the same compounds in both their RCs and FB papers.

Since New RC and FB are both using the same emulsions but have different bases... will modern papers hold up as well as their grandparent's papers? Which one is better if both emulsions are the same? Does the base material realyl make any difference if the emusions fail?
I think that you have hit the crux of the problem there Paul. It makes sense for a paper manufacturer to use the same emulsion mix on both their RC and Fibre papers, and most do. The problem of delamination of RC papers dates back to its early days. Today it is only a problem if the prints spend too long in water, over-washing or too long in toning baths for example, or at least that is my experience. Trimming the edges off the finished print effects a cure. The only thing I can be reasonably certain of is that either type will out last my pigment inkjet prints I think!
