Mark and Sander, thank you,

Will try to keep it as simple as possible with Rodinal so this 
information is welcome. I did see some variation what the minimum of 
pure Rodinal per 4x5 that should be in any mix, some think 5 gram is 
enough, Agfa says 10 gram.
I guess I can do the maths on the quantity needed in the Jobo tanks to 
get there.

I used to presoak in the past, even with the small Kindermann tanks and 
with little agitation later on. More as a precaution against air bells. 
At one time I did throw out all the equipment and the chemicals but not 
the development menu. The fact that I used formaline to harden the 35 mm 
films must have been the wisest decision then if I consider the less 
than archival treatment they got over the years. Don't think I can buy 
that as easy as it was possible then.
