I'm a rank amateur and a beginner at 4x5, without a darkroom to boot... so FWIW. I started using my Patterson without the reels: not recommended unless scratched negs is what you're after. I bought the Jobo 2500 tank, and use it manually. It holds up to 6 sheets and after some practice, isn't all that difficult to load in a changing bag. It does not leak and drains very quickly. The only drawback is that to fill it requires 1500ml, whereas used on a processor, it would require only 270ml.
So on that front, and having never seen how processors agitate, I wonder if I could use reduced amounts of solution, and "simulate" the movement/times a processor uses. What is it, constant rotation with the tank on its side?
