I do use this method but the leaf she is string on her side of the stick is not getting the proper twist. the side away from here is. this stringing method was designed to prevent any leaf from falling during the fluecuring, it has a twist in the string that tightens as the leaf shrinks and it works most effectively at keeping the leaves in place. there is another video on youtube where they were using a mule drawn sliegh to bring in the harvest. the girl in this video is very fast at string and needed two guys to pass her the leaves. the stringing in that video is more on par with traditional string and is where i learnt to do it. i'm able to string 80 leaves per stick on 20 sticks in a day using that method (1600 leaves) if you've harvested them the day before.
I agree with what you are saying about one side not having a 'locking' twist. (I made that point in Post #6, above)
I'm pretty sure we're talking about the same thing but I originally said that it was the side away from where she was standing wasn't getting a locking twist - this was because (without checking the video) I thought she was standing on the other side of the pole from the guy handing her the bunches.
I've been standing on that opposite side and it works fine for me.
I still haven't had anything drop in the flue-chamber, though a few loops have sometimes sagged a little.
