What are development times in D76 or Rodinal for J and C classic ISO 100 black and white film? I'll have two rolls of 120 here shortly and I'd like to know what to use. I'd like to use the D76 1:1 and Rodinal 1:100 if I can.

From my own experience:
- The film is an overall good film, nice tonal range, decent sharpness, grain is comparable to Plus-X
- Speed is about 64-100 (from my own tests)
- Base is clear,with a tinge of blue
- Anti-halation back leaves a deep blue wash in the pre-soak (looks like the toilet tablets) but is gone after 3 changes of water and agitation
- Rodinal (1+100 30 minutes, 1+50 14 minutes, 1+25 9 minutes)very well. Prints well in grade 3-3.5 DDX 1+4 7.5 minutes (EI closer to 100)
Due to the nice clear base, negatives look underdeveloped but there is plenty of shadow detail
Caffenol is specially good with this film, and Caffenol C is even better
- I have seen some pinholes in emulsion specially towards the edges
J&C Classic, shot as 100, Rodinal 1+50 14 minutes (agitating once/minute)
Rodinal 1+100 30 minutes (agitating every 5 minutes)

Thanks! I could do the once every five minutes thing easily...kind of a semi-stand type thing. Maybe I'll try that with this next roll.
