I've used deep tanks with hangers, trays and the Patterson Mod 54. I find the Patterson Mod 54 to be the best fit for the volume of 4X5 I usually do. It takes a time or two to get comfortable loading them, however after that you will have no problem. If you go the Mod 54 route, check out their youtube video on how to load/agititate using their product. Bill Barber
