Thanks guys. I can see that I should have been more specific. By "best," I am referring to the quality of the developed film, NOT value, ease of agitation, or waste. Also, I should have specified that I will be using a Jobo processor. I will not be hand agitating. I should have also specified that I my question pertains to E6 processing only.
The vast majority of my shooting is on 4x5" and 8x10" film but I wanted to know which drums will produce the best results, qualitiy-wise, when used to process E6 roll film in 35mm and medium formats using a Jobo processor. I will be using expert drums for my large format film.
I will not be processing b&w with the Jobo. Yes! I know how people rave about it for that purpose but I have been processing in trays for decades and I have no problem with it at all. I can't even remember having a scratched negative and my development is very even. When I have very large amounts of b&w sheet film - for example, after a long trip - I process in a line sink and I have never had any of the problems other people have reported. Most importantly, I have my development times down pat and I simply don't want to go through calibration testing again. Bottom line is that I will only be processing E6 with a Jobo processor. I should have specified that in my original question.
Anyway, with that cleared up, are your suggestions still the same?
