The smoothest, most reliable rewind method is simply to use the built-in lap dissolve function, which the more sophisticated s8 cameras feature.
None of them permit more than a 3-second dissolve because this is the amount of slack the cartridge design permits before the coaxial core locks, as has been noted.
In my experience, the old silver Nizo Professional models offer the smoothest lap dissolves, w/o the tell-tale 'pop' at the end.
All that said, I happen to have a Russian-made super 8 cartridge that is reloadable! It comes a part into 2 pieces. And until this thread, I completely forgot I owned one. Never got around to experimenting with it. But I believe this would work perfectly for multiple passes.
Rather obsolete in the eyes of many these days, I suppose, given the possibilities of digital editing. In fact, I recently had both my Canon 1014xls's serviced, including having the lap dissolve button disconnected. Due to its placement, I kept hitting it by mistake. And I figured I could always superimpose later in Final Cut.
Anyway, the Russian-made cartridge might be found on Ebay.
