No productive suggestions on use, but it was a lovely paper. I only had it in the G surface, and did some extremely nice environmental portraits on it. It had a warm faintly greenish color when untoned, which when combined with the cream base, is very pleasing. I'lll admit that I had to look at a print under bright daylight to agree with green, as I just thought of it as an organic black, over a very pleasing cream base.
One of the few cases where to prefer the Kodak over the Agfa product. Ektalure was gently warm, whereas Portriga was brown.
Finally, maybe you should consider selling it in single sheets. It was truly a loss when it was discontinued.
