SonrNYC, I've seen those reels here and there as of late, are they some sort of new design?
- Can't seem to remember seeing them before at least.

It was curling, as though it wanted to get back onto the original negative take-up spool.
Indeed, up here (when this situation occurred) it is very dry and cold (During winter, I actually need to use body lotion after showers, because my skin dries out).

Simon clarified nicely the reason why I got the immense curl I got with my film that day, so maybe your humidity suggestion isn't so far fetched.
