Hi, This is my first post. Getting back into the darkroom after many years. Been doing the digital route and although I still use digi I still like the look of film. So anyway I have a couple of jobo processors cpp2s. One of many questions to come is, What are the advantages/disadvantages to using the 4x5 reels vs the 2006/2010 tanks? What is the difference between the 2006 and the 2010 tanks. They look the same to me. I'm getting ready to buy one ir the other.
