I have about every combination of film drum that fits the CPE2+. The hassle is I don't have a place that I can leave it set up. So I have to deal with the water bath for no reason ( also don't have water or a drain in a real convinient spot ). I like the Jobo and use it for E-6 and C41. Yes, I could use the small tank but I don't have a roller for it and I just thought it would be entertaining to get the Unidrum going again.
