12-exposure rolls of Kodak Gold are still available here and there in these parts. Only had a brief fascination with them.
As for Ilford's 72-exposure HP5, I had a brief and traumatic experience with it, via my old Canon F-1 and Motor Drive MF, which, let's just say, was a real MF to use with such a thin-base film such as that. Never liked the prints made from it, either.
