I stopped loading cameras with film unless I'm taking one for an outing because of the following:
1- I forget what type of film is loaded in which camera.
2- I like to keep the time between film-in-the-fridge and film-in-spiral-tank to a minimum. usually less than 12 hours.
3- when I'm bored I like to play with the cameras, cleaning them inside and out, dry firing the shutter and just general fondling. That, of course, would be difficult with a loaded camera.
