Now I have a couple of
Alden 74 loaders. They are far nicer than the other brands I have used.
Don't load more than 36 exposures into a cassette unless you want scratched negatives,
not to mention difficult advance and rewind. I too prefer to load 24-30 frames per roll.
Use strong tape to fasten the film end to the spool. I recommend
3M Scotch Super 33+ electrical tape.
It is strong, remains pliable when cold and stretches a little if required (e.g. with motorized advance).
Another nice feature is that it peels off perfectly clean, leaving no adhesive residue.
Some cheap masking tape I used once broke in the field. That exposed film was in my only body.
It was
game over until I could get home and unload the film into a daylight tank in a changing bag.
Try not to be too frugal attempting to use every available frame.
You'd hate your next masterpiece be ruined, half of it exposed to daylight during loading...
