>But, when Fuji stops production (which I'm sure they will)
Oh no, what a nightmare this would be! I hope this will not happen... Acros is a wonderful film. I have around 25 rolls (120) left in my fridge and will re-order soon.
(My personal disaster would be the loss of TriX - it would hurt like the loss of Polywarmton - but I'd surely miss Acros as well. These are my two main films.)
