1. paterson tanks are good, but
Freestyle brand/KALT/BESSELER spirals are the way to go. They have a wider "lip"to start with the film and that for 120 is a blessing. I guess JOBO are similar.

I have never been able to go with stainless spirals but I'm just a weirdo.
2. Caffenol is a funky developer tha works just for fun, in 2004 Donald Qualls, your truly and several other in photo net and APUG did many improvements and research.
