I've been experimenting with caffenol-c printing. I bought a large box of misc papers from a guy getting rid of his darkroom to experiment with. I found one in the box that responded quite well to caffenol, giving a nice light sepia colour to the highlights, but still nice, rich blacks.
Unfortunately the paper was in a box (Kodak Polycontrast III RC) with a handful of other paper, so I'm not sure what the paper is. I'm pretty sure that paper is long gone and I won't be able to find it any more, so I'm looking for suggestions from the Apug world of others that respond well to caffenol.
