I've gone with 70. I don't think it makes much difference which one you pick. But I'd not switch around. I'd pick a temperature and stick with it from then on for everything. A certain film is not going to need a different temperature from what i can see. Just a different time. But on the other hand I've heard there is a new trend to develop at such temps as 75 degrees with the T-Max films and all which have come out. I hear that such a higher temperature works out alright, shortening otherwise very long developing times. But I've been doing 70 degrees since about 1970.
