I think this thread needs to end. You're all coming from different assumptions about and requirements for why one might stockpile film and talking straight past each other. It's pointless and just makes the lot of you angry. If the OP wants to stockpile, that's his prerogative and the merits of doing so are pretty irrelevant; I think they could be considered thoroughly warned as to the risks of keeping film by now.
Go forth and rotate your stocks (whether they be 10 years or 10 days worth) through your cameras please before someone has a stroke.
