4x5 Developing options

I have use an old Unicolor 8x10 processing tube and their Uniroller for years.When I got back into large format I dug out the old processor from the days when I did color printing(never throw anything away) and it worked perfectly The 8 x 10drum holds 4 sheets of 4x5 film within slotted guides and a rubber separator .Never had a film touch another one during processing. The continuous agitation is more or less countered by using a large enough volume of developer. I use 500 cc's of HC-110 1:50 or D-76.full strength. However as I use cold light enlargers I prefer full bodied negatives. You can probably find one on E bay for a song
