Hi Simon:
The only way I'd likely use amidol is as a way to fine-adjust between grades when using graded paper with a water bath. Gallerie seems to be the only truly dependable option anymore. Otherwise, I'll probably stick to VC and Ansco 130 with benzotriazole. The only issue is my film developer of late, WD2D and the stain which may or may not render tonality adversely with VC paper. I'll be able to test in a few weeks (after this present job- I'm in the middle of nowhere in South Carolina right now), and will report back! I was going to test Seagul and MCC110 on the VC side but perhaps I'll now throw in the new Ilford cool tone VC to compare. I was just never thrilled with the neutral MG historically.
***Simon: How would you propose making fine contrast adjustments to Gallerie between grades when printing? With VC I've always used a color head and made quarter-grade or less adjustments. I'd like to maintain that level of control.

For a thorough discussion of the Chinese amidol problems and solutions, including assays of impurities, take a look at the threads in the Azo chemistry forum from around the middle of 2006 to 2008 or so:

Michael A. Smith has been using it and said he didn't have any problems with it, and many users report no problems, but it could be that there are impurities reacting with the water in some areas, but not in others, or with some people's processing trays, but not others.
Thanks Doremus:
The way I've heard about it is the harder developer first, and then the softer developer. Does it make a difference which order it's done? If I want a version based on Ansco 130, perhaps the trays have nearly the same formula, same amounts of metol and glycin, but only varying the amounts of hydroquonone in them: one with a pinch extra, and one with maybe 20% of the formula's usual amount? Good starting point? Is there a minimum time in the harder developer to insure a minimum black? What times would you suggest? Should the time in the two trays still add up to 2.5 minutes?
