I actually tried a roll recently, out of pure curiousity. I don't think I will be going back for seconds. Not that its a bad film - very fine grain for a 400 film, seems to have a nice tonal range... but: its great when your exposure is spot on, when it falls apart, it really falls apart. I know - this is my fault for not getting the right exposure, but I shoot a lot of available light stuff where I am on the ragged edge of what light I have available, and when even slightly underexposed the film gets that ugly, mushy grain that looks like a rash or something...
As far as printing, I found slightly (again, very slightly) more exposure required, and the difference in contrast is there, but its very slight - I have not found any consistant need to go up a whole filter grade or anything. In light of that I am willing to deduce that the differences are probably in the scene itself and how I personally want the image to look, not in the film to any large extent. The last thing maybe just a personal obsevation at all, but it took me a few minutes to get my focusing right - I think its just a matter of looking at something that looks different than what you're used to.
Overall, not for me - but a perfectly viable option.
Peter.
