I totally agree with you Bruce. I own a zone 6 washer and a zone 6 washing machine and they do work and own an Oriental 20x24 washer and they all do the job. The concept that fixer is heavier than water was his mantra. This may not have started at Picker but may actually have started with Adams. This was a very effective sales tool for him and I don't remember anyone taking him to task for it. That said there is a theory that if fixer is heavier than water, then fixer would not mix or at the very least STAY mixed for very long. It does stay mixed together, but some of the non-acid fixers do separate after several months and that is another story.
