That is what I did (and said in post #40). By default, the rails in the camera are set for 120 (film + backing paper), thus a flat pressure plate pressed against the outside rails provides the correct gap to hold the film flat against the film rails. The 220 back has the pressure plate machined away where it touched the outer rails so that it makes up for the paper backing thickness. This is what I did (plus the flipping the plastic thing).
Re: 50 rolls of film. That is about the # of 120 rolls I shoot recreationally in a year. It about 2 wedding worth if I'm primary - although the last time I was primary, only 1/2 was 120, the other half was 135 (and that was a long time ago!). When I'm not the primary (ie: shooting guest) it's 5~10 rolls.

I've figured this problem out.
It’s not the shutter, it's a light leak where the back meets the body.
Light gets thru the gap and shines on the most recently shot frame, which is partially rolled up onto the top reel. The line is a shadow cast by the reel. See this diagram.
SOLUTION: New seals, or a new back, or black electrical tape to seal up your leaky gaps.
