Powdered teflon in the tip does no good. Even though the problem only happens on some piano, it could be a cracked tuning tip head. I had the problem you mentioned, but only on some pianos, and not others. I looked very closely at the tip, and discovered a small hairline crack. What effect it had I am not sure, but when I changed tips, the problem went away. I am guessing that because of the crack, the tip became "out of round", or "out of star". In other words, to tip wasn't exactly a star shape any more, and I gues this was causing the tip to get stuck on the pins. Like I said, just guessing, but the problem went away when I changed tips.
