Hi Bill,
I tried the Fomapan 400 Iso and I gave it up because it was not satisfactory, but a deeper investigation was necessary (I tried only very few rolls). On 35mm I use almost only Tri-X and the Foma was not the same. On 120 format maybe I could give it a try, but so far I'm sticking on Adox CHM 400 because it is the cheapest I can buy (I'm still learning how to use the Hassy...), for sure not the best one too.
About the paper, I tried the multigrade RC, I don't rememeber the exact name. I have been really disappointed by it - I come from Agfa MCC and the Foma is not in the level: pretty thinner, I found some uneven coating and there are ESD taking the foils out of the bag (!!!!) that leave marks... never seen anything like this before.
So, my point of view is that if you are on the budget side it can be worth to try Foma material, with some attention on the handling of the paper. If instead you want high quality, you have to look for something different.
