"Can anyone compare it with Tri-x for me? Anyone shot it side by side, same developer etc? The Arista Edu Ultra is about the same price as the Arista Premium, which we all understand to be re-packaged Tri-x. There would have to be some real differences, advantages to the Foma for me to try it, but I'm very interested."
I have heard people say that Foma 200 felt somewhat like the old Tri-X 400 to them.
I'm not sure about that comparison. If I were you, and I wanted to find out, I would try for myself by comparing them side by side, as that is the only opinion that really matters to you anyway.
