He he at my age I don't change ANYTHING! hehe
Except I've picked up a few newthings, since this digi revolution, but the old stays the same, only difference I make double sure before every move.
I changed over to Rodinal. well before computers hit us, giving up on Acufine and D-76, Rodinal suited me more, if I want fine grain I change FILM, not developer.
I don't plan on changing that either, even if good film is hard to come by these days.
