I spend most of the time on test prints, instead of the final prints. For large prints, I have several large drums, like 28xx and 3063. They are good for one day's work and I do not really have to wait for them to dry. For test prints, I mainly use test drums. I can just try them with towels. It is not too hard. I still print test strips to calibrate my Colorstar, then use 4x5 for to test print. Colorstar does cut down the numbers of test prints, but I can't trust it 100%. So far, this process has worked well for me.

I still print B&W with open trays. That is a different story.
