I've useed Eastman 5222 (Double-X) without using a hardening fixer and it's no problem. Remeber that this is motion picture film and as such is meant to run through automated processing macines capable of running thousands of feet of film in a short time. Rougher handling than we would consider prudent is expected, therefore the recommendation for a hardening fixer is given. Hand processing on small reels is a much gentler process. The usual caveats apply, use a good wetting agent and do not use a squeegee. That said, it's not a film that I'd go looking for again. If you are expecting it to look like Plus-X, forget it. It's very grainy for what it is, and it's not designed to print well on photographic paper. At full retail price, you'd be betterr served with Tri-X. If you can find short ends at $0.15/ft. go for it, but at full retail I'd give it a pass.
