I hope you see my POV.
As for the later comments here by Mr. Berger, there are some points that I would differ with. For example, Ilfochrome does retain some of the dye fragments after processing, just as Kodak and Fuji products wash out most harmful ingredients and leave behind dye stabilizers. I agree with his comments on the stability of supports. Much has been done on the stability of Kodak and Fuji supports, but what has been done on the UltraStable suppor?
Again, we just have to wait and see.
