Every now and then I read a post stating that Spur's HRX-3 developer is a viable Xtol alternative. Can anyone comment on this? I am about to experiment with HRX-3 combined with Rodinal as stand developer. I know that very good results are within reach when doing stand development using a mixture of Xtol and Rodinal. But the 5 liter Xtol packaging is too much of a burden. Hence my reach for a alternative.
