Ilfonal! I like it! Maybe I should see if it can stand develop like Rodinal...
It'll probably do a better job at high dilution, long agitation interval processing procedures than Rodinal - not least because it's actually got decent buffer capacity, so it doesn't keel over after 20-30 mins. The shadow speed may be less than that of Rodinal at normal contrast ranges for silver printing - Ilford suggests about a 1 stop under box speed rating when aiming for a normal 0.62 G-Bar, and box speed at 0.8+. If you don't need the speed & contact print, there's little to touch the flexibility of PQ Universal in contrast control etc. Produces a pretty decent straight line sensitometric curve too.
