Wondering if people are loading the film with the film sheath installed in the holder or are loading the sheath removed from the holder? I'm trying to find the best way to keep my fingers off the film. Looks like for film removal the best way would be to pop the sheath out to remove the film. My holders have a small indent to allow a fingernail to reach in and push the sheath downward for removal But I've having a problem putting the sheath back without pushing on the top corners to get them under the lip. And that puts my fingers on the film. These things are sort of a PITA compared to new film holders.
