The EDU ultra is re-branded Foma. From the results to the blue tint (at least on what I have in 120, this may have changed recently according to reports and I never got it on 4x5) to the green/blue dye that comes out in pre-soak, it's clearly Foma. Pretty nice film really if you like an old school look. I too have been shooting the 400 at EI 200 with good results, developed in D76 1+1 at about 15% less time than the spec sheet calls for.
