Gerald, I understand Kodak recommends HC-110 but this is more of an experiment I'm doing to see how my Tri-X will do in Rodinal. I've tried pushing Tri-X in Microphen as well and liked the results. Going to try HC-110 after this push in Rodinal .

Jim, thank you very much for the response. I know this is probably a moot point since pre-wash time isn't a HUGE deal but by several minutes do you think ~3 min should do?
