Just send me the plus-x and I'll put it on spools in cans for you. Of course you may find it's only 300' when you get it back ;-)

The ideas here will work ok but it's imperative you keep the 400' roll flat on its side on a stable surface (preferably on some sort of axle rod) so the film doesn't fall off the core and make an unfixable mess.
