Thanks for putting your thoughts and your impressions based in your experience out for us to draw from. I agree that I have seen some really fine prints from Azo...but then I have also seen some very good prints on other papers or printed with other processes.
I think that the marketing hype surrounding Azo was part of the cult appeal of the paper. It was certainly good...but as you said it is time to move on.
The paper does not the photograph make.
