I also use one of these, and I find it to be much easier to load than the HP Combiplan holder. I have discovered that very gentle agitation is an absolute necessity for using this holder in the Patterson tank. I agitated a little bit to vigorously and had a sheet of film get ruined as it had several areas where the emulsion was scraped off. I have done very gentle agitation since then, and I have not had any problems since then.
Thank You Morgan for making these processors. I have put mine to good use by processing 12 sheets of 4x5 sheet film every week for a photography class that I am taking this quarter.
Glad your getting the hang of the processor, yeah you have to use gentle agitations.
