the paper flattens out
I haven't bought the edge, but the Fuji CA, and it was fine. nice too, cause I like the 10x12 paper size, and cutting those down from 12" or 10" rolls is sooooooooooooooo convenient, rather than buying cut sheets, which are IMPOSSIBLE to find from Fuji, even though they're supposedly cut :mad.
its a great way to get some money savings though.
just be aware that the exposure times for the roll papers are generally shorter, like 1/2 the time or less, so be forewarned....
