Clean the hell our of your reels. Really. Make sure they are COMPLETELY dry before you load them, always. Sacrifice an unexposed roll (or one of these damaged rolls) and practice loading them again. Make certain everything looks right. Use a flashlight and check to see the rolls are not touching. As mentioned, check for burs on your reels as well as your 35mm camera and your 120 back.

It looks like you've got a couple issues going on here. Stop developing film from your trip. Photograph something you don't care about and get things worked out with that film before you start working on your important film again. This last part is the most important. Trust me. I've been there and I understand....
