I use "old" D-76, too. I usually dilute 1:3, and process at 66 degrees F. The results are fantastic with HP5 (@200) and FP4 (@50). I think there are many combinations that will work nicely. I've heard good things about the T grain films in Perceptol, although I havn't studied this combo, myself.(posted 8522 days ago)Good luck!
