I just posted an image in the Experimental Gallery that I developed using Rodinal as a paper developer. While the negative is not as sharp as I would have liked, the results did convince me to try Rodinal again as a paper developer. I used a 1+10 dilution, but I think you could work with that and find what works best for you. PF has basically a Rodinal kit, you just add water or if you want to order the real thing, I suggest the 500ml bottle if you plan to try it as a paper developer. The 125ml bottle does not last very long as a paper developer. BTW, get a copy of the Darkroom Cookbook, it really is a great reference.
