Generic backing (if it's possible, one like in the Eastern European films (Fomapan, Fortepan) - the black one with white large printing, that's so convenient and it also reduces the opportunity of fogging through ruby window, compared with usual Ilford white). BTW, Foma and Forte use the same backing for their films, but their end stickers are of course different. Gummed paper stickers, please - it's just safer in my eyes, I had problems with self-sticky things in frosty time. And the film-retaining sticky paper inside the roll shouldn't be so tough and difficult to rip - again, the sticky tape used in Foma and Forte films is like a paper scotch tape, ripping very cleanly and with no risk of getting some of its glue on the reels/emulsion. I've had also problems with the glue from sticker contaminating the reels of my Kaiser tank, making clean loading way way difficult if not nearly impossible.
I still use ORWO 120 aluminium cans for my roll film, and I think it's not yet a time for Ilford to waste money on these - the containers are nice to have, but I always needed just a limited number of them. They would make film much more expensive, of course, and most of them would find their way to bin.
