Well, I shot both 120 backs this morning. The 120-i back I initially had that has been giving me issues is still stopping short (around frame 7/8). The regular 120 back did great. I put some Zippo lighter fluid onto the gears though earlier this week to try and loosen any dirt and such as it was giving me some issues before. So once the film is done in the 120-i back, I'll do the same thing with the lighter fluid and see what happens. Now the other question is anyone near Oklahoma City that I could buy a roll of 120 film from to run another test roll through ? I'm currently in Lawton, OK with my in-laws and will be leaving in about a week.
