Diafine: phenidone/hidroquinone/sulfite/metabissulfite in bath A; sodium metaborate (Kodalk) or borax (not sure which one)/sulfite in bath B.
My film/dev combos (only 35mm):
- 125 PX in a Xtol like dev 1+2 for normal work - fine grain, sharp, good tone, higlight control. I really liked this combo.
- 400TX in Diafine like dev for available darkness. Same reasons Lex stated above.
Have used HC-110 in many ways and FX-37 with PX. The above is better.
Did not like TMX.
