tried them all again yesterday, Tape still doesn’t seem to make a tight seal, the automatic hog rings dont close up enough and can be slid off the end to the bag. in the end i went back to the single hog rings. my technique improved with them as i went, will probably use them again next time. Still quicker than tying the bags.
Spun as tight as I can get them and zip tied. Found a package a couple years old at the bottom of the freezer and it was still as good as any other package I’ve ever had.
