Tried TMX, TMY-2 and Delta 400 in Caffenol, TMX in R01 and HC-110, TMX and TMY-2 in TMAX developer, and Delta 400 in HC-110.
But have to say, Acros is the best I've tried, both in Caffenol, and in R09 (medium format, a bit too grainy for my taste in 135). Unbelievably smooth tonal gradation. When that goes, I'm going into mourning. In Caffenol it can easily be pushed, but I prefer not to go over EI 200. Neopan 400 also very good, but sadly gone. 1 roll left
Delta 400 in Caffenol also works well, better than TMY-2, a film I never really got the hang of in Caffenol, nor TMAX Developer and therefore have sacrificed for Delta 400 (and Neopan 400). In fact for 120 I prefer Tri-X in Caffenol, HP5+ too.
TMX works well more or less in whatever I have tried. But can be a bit contrasty in HC-110 if not careful. Best in Caffenol, at least for negatives that are going to be scanned (smoother tonal gradation). I don't use it much because Acros is better, but if the latter is taken off the market, then TMX it is.
