rbilersky: I would take Ken Norton's comments on Perfecta pretty seriously. He is a very respected printer and good photographer, with a wealth of experience. He contributes in depth on the OM list, and I respect his opinion enormously. You can see more of his thoughs on Perfecta at <http://www.image66media.com/page16.html>
I have not used Pefecta, in fact I have not printed in years. When I was printing, I settled on Zone VI Brilliant in Amidol. When I start again, I will be teting Perfecta with both the companion developer and Amidol.
