I have only one potential Studional caveat and I haven't yet tested it.
According to the 2003 Agfa Studional MSDS, the developer contained Potassium Sulfite.
According to the 2007 Agfa Studional MSDS, the developer does not contain any form of sulfite. Without sulfite, the developer should produce image stain and tanning.
Image staining and tanning is fine with me, but it may not be ok with some folks.
Of course, to prevent staining and tanning, you can always add a few grams of sodium or potassium sulfite to the working developer solution.
