How would you develop it? (Nobody else would) Sounds like a royal pain in the butt to me. Rollfilm is such an elegant solution. Better enjoy it while it's still here. I bought a bunch of Type J single sheet holders for the Mamiya one time. Shot half a dozen. Figured out they don't fit into anything for development (Jobo 2500 series) and they're in the freezer to this day. I need to put those holders on feebay.
