I was using a unicolor drum for 8x10 until I switched to tray development a few weeks ago - it works really well.

I did have a small problem with increased stain/pressure marks/somethingorother along the ribs with Rollo Pyro (invisible on the neg, showed up in the print). Apparently Pyrocat works better in that situation, but once I got my Pyrocat, I started doing it in trays.

Anyway, back to the point, I also suggest the unicolor system...
