I get excellent results with Ilford WT in Caffenol, a different and fun way of printing. I've done some pseudo-lith printing (following the lith methods, but no infectious dev... just waiting until the blacks are right to pull the print) with both the FB and RC papers, and the results are promising, if not true lith. I'd love to try this with some more lith-able papers to see if I can get more of a lith feel.
A few years ago I experimented adding KBr to Caffenol, but it appears rather than acting as a restrainer, it pretty much shut down the process and wasted several sheets of paper before I gave it up.
But I digress... Ilford WT are lovely papers, and if you like a particular developer, have at it.
Cheers,
Tom
