Have had that first bottle, 5Kg as you say, going for nearly 2 years now, don't need any more trimming lol, as just cut out four containers the other day as you saw. Need better colour low down hence our ATI discussions. I increased the bubble count to at least five or six a month ago, after your out burst. not bad at all, but the quality varies and I understand you get different grades with coloured stickers - yellow, blue, green I've had. I'm told it''s better to get one off a ship, that has good specs and quality rather than a Ch import even if it has a few rust spots on the bottom, but way out of my depth here..
