I have the spiral reels from 20th Century Camera to develop 4x5 as well as 2x3 and 6.5x9. Since I知 slowly moving towards an 8x10 setup, I知 looking at the best way to develop. Their 8x10 spool holds two 8x10 sheets in a 5-reel Paterson tank:

Tray development is out, but I知 open to other ideas. My biggest need it it has to be a daylight tank of some kind. My main concern with the 20th Century reel is whether it will develop evenLy. The 4x5 reel works fine, obut this is a lot taller, and the film is spooled more since it has to fit twice the linear dimension into the same diameter tank. It will also use a lot of chemicals if it is used upright with normal agitation, so I may want to find a small tank roller.

Has anyone used these, or can you recommend another daylight tank to develop 8x10?
