Tom, all my AZO contacts are developed using a catechol paper dev and Neutol WA. Lovely tonal rendition and control of highlights. I would characterize it as mid- to high contrast in effect, which is why it typically is the second dunk in my procedures. I love it with AZO. As far as I am concerned it beats my Amidol developed prints and is more convenient - I no longer need to have powdered chemicals around the house as they come in a liquid kit form.

I always use Nitrile gloves and I do not slosh my prints in the trays - I use my gloved hands to make sure the paper is under water and then I leave them lying there until their time is up.
