I very much like Polymax FB glossy that is air dried. I have some on hand. I bought a 100 sheet box from Freesyle of Arista EDU Ultra gloosy FB DW 100 sheet 8x10 paper for $35.99.
I was ammazed in how vwry closely the two papers resembled each in speed, contrast, print color and gradation. I also formed the opinion that the Arista paper is quite easily fogged by safelight. When keeping the developer, stopbath,and fixer trays in the shadow of the safelight and not being able to illuminate the interior of my paper safe or easel I had no problems. I have not yet toned any of this Arista paper and therefore I know nothing about its response to toners.
I bought the paper hoping it was worthy of use. If you want a good emulation of Polymax, you may wish to try this paper. Don't blame me if your wallet stays heavier than it would were you able to buy Polymax.
