Lets see those results! I'm rather fond of paper negatives!
My personal paper of choice is Ilford RC @ asa6.
I have never used the Arista paper, and am just now starting to test the Arista EDU 4x5.
Good luck with the paper negs!
I think this was my best shot. I used a Toyo camera and Arista Fiber paper rated at ISO 20, then just developed by inspection.
