I have no doubt nor dispute on Amidol's capabilities. My goal is to arrive at developer/paper combination that gives equal results to my eyes, in order to get away from the limitations, and now huge expense, of the availability of developer and paper. I don't feel like I'm compromising anything. As others have said, the Amidol/Azo combination is very easy to use. But I don't think it takes much more effort to use these alternatives. Its just getting back to basics and using them effectively.
