True. This tape is acting differently than any other tape I have transferred before, video or audio. It is not back-coated, squeals, and sticks. It makes me think that maybe our assumption that SSS is caused mainly from the back-coating is not necessarily true all the time. This tape so far behaves just like a classic SSS tape. And being so thin makes handling it even harder. I have placed a batch of 14 reels in the oven overnight. 10 blue and 4 green reels. I'll check them tomorrow and report back.
