What do you mean under "still"? I started with film for real in 2012 and it was no brainier to switch to bulks in no time. Five years later it is the same.
I'm using dirt cheap films to load my re-usable cassettes and check if camera I fixed is actually still working.
Do you think I need five backs per individual roll of film for it?
Seriously, where I'm bw film is next to none exists and I have to order it on-line. And shipping in bulk makes sense. Isn't it?
Anyway, the good bulk loader is the one which has short distance from film container opening to where the cassette spool spins. It should have working frame counter. And to make this good bulk loader even better, I super glue welt from single use film cassette to the edges where it goes from film container to the cassette area. Less scratches.
Masking tape is in use to hold spool and film. I use scissors for tape and film.
