Thanks. I'm a big fan of very selective focus whenever feasible. To do this I actually have modified a spare takeup reel so that I can load the 35mm can in the same location as the 220 film in a 220 back. I use the 220 back to get about 15 or 16 shots per roll as opposed to only 10 with a 120. I tape a leader of 120 backing paper to the 35mm film to start it winding on the takeup real in the proper position. This way I can shoot as normal, but I do need to rewind the film in a darkbag by flipping the spindle for the takeup and then rewinding the canister by hand. Here's what I did to fit the 35mm can in place:
