I must have blew through 60 sheets of 4x5 before I employed most of the rigorous dust control tips offered here and cut out the BS and bought a 3010 Expert Drum for my previously unused & donated Jobo CPP2. Unless I am running a couple rolls of 35 or 120, I use the Jobo for everything. No dislodged Rollei IR, no streaks, no pitting, no BS.
With good black and white 4x5 sheet film costing between $1-2 per sheet, I need 100% consistency and the only way I have gotten that is with an Expert Drum. But it was the nasty dust issues that had me seriously thinking of dumping the format. Ruthless control methods have helped out quite a bit and I now feel that I get the pro results I need.
Mod54 has an updated version of their popular Paterson tank insert available that has improvements in regards to both loading and build quality. I have one left and while I think they are a great solution to those of us who have no way of tray souping, the problem I ran into was films with really thin base material like Rollei IR 400 coming dislodged and getting ruined. They also use 2-4X more chemistry than other methods.
