I have a chance to pick up 3qts. real cheap (free) from a mate of mine who is relocating to Australia. In doing a bit of research I have found that it was a favorite of Ansel Adams so it seems like a good choice. I am trying to standardize my film developing and HC-110 looks like something I can stick with for all my Tri-x work.
Before I take the plunge I felt it necessary to ask fellow APUG members their experience using said developer. My FP4 and PanF will continue to be run through Rodinal.
