Thanks for your comments. I see your point.
Just for the record, I don't use a Jobo. These units simply take up too much space for my workroom. I use Beseler and Unicolor print drums on the Beseler and Unicolor motor bases built for these drums. This type of equipment is cheap as dirt on ebay these days so we are talking about tens of dollars as opposed to hundreds or thousands as with Jobo, and for my money the results are every bit as good, so long as you observe two precautions: 1) always pre-soak the film, and 2) take the drum off the motor base every 1-2 minutes and give it some vigorous sideways agitation to counter the one directin agitaiton it gets on the motor base.
