Grain and Rodinal
I don't have a direct comment, but you might try Spuersinn HCD-2 and HCD-S developer, available from www.ag-photograhic.co.uk or www.keyphoto.com (both of whom will ship abroad). HCD-s produces bright, crisp iamges on a wide range of films, with good tonal range. but you can vary the degree of graininess you want by varying dilution, temp and whther you use it as one or two bath. Full instructions included..and it does push and pull process well. It is German-made, so they understand the Rodinal users, and if it suits your photography might be an interesting alternative.
