I've recently switched from Kodak T-max to Fuji Neopan for all my b/w photography. I did that after test sessions where I shot both with Kodak and Fuji. I'm much more satisfied with Fuji, and I find it odd that nobody else on this Forum has ever mentioned anything similar.(posted 9825 days ago)I guess it's due to the fact that photographers are creatures of habit: they stick to certain products and labels.
Anyway, you didn't say in your message if you have tried Neopan yourself, or hust wanted to hear an opinion from someone who has, but I can warmly recommend Fuji's b/w films to anyone (and I'm probably gonna get flamed beyond recognition for saying this, by other memebrs of this forum). The grains are finer and the contrasts less "edgy". Very good, indeed.
Hmm... you asked about the possibility to push it to 400? Well, I haven't tried that, cause I mostly use the Neopan 400 directly, but I've pushed the 400 to 800 and 1600, without any problems, so I don't see why the SS wouldn't work.
Go for it!
