The paper isn't here yet, but they did testing during its development. The paper itself has been ordered and they're pushing to finalize production before the humidity of summer sets in. The last I heard, they had something like 70% of the money they needed to pay for production in the form of advance orders. The details are all available on the Azo forum at their Website (www.michaelandpaula.com).
Hats off to them for undertaking this. I've been experimenting with various enlarging papers since the demise of Azo and I just haven't been very impressed with anything I've tried yet.
