i put a roll of 120 in the camera with a nickel on each side as spacers to make the roll fit right. so, i can load in full light. then i use the 616 takeup roll as normally one would and unload the camera in a changing bag and then wind it onto the spool of the developing canister. no light leaks that way and no tedious winding of film onto a different sized roll. try it!
