i would also like to know about an un-official "official" line.

I know that information! What I don't know is the pre-monster pit line... the un-official "official" line... before 8:00AM.

Line opens at 8:00 a.m. At 9:00 a.m. BTWB staff selects people who receive monster pit key or numbered wristbands. After this, the line shuts down and we're encouraged to go be somewhere warm. Then the line opens back up (for people who received a pit wristband) at 4:00 p.m. If you receive a wristband, there is a designated time for you to experience the Born Brave Bus from 3:00-4:00 p.m. BTWB staff takes pit wristband holders inside at 4:00 p.m. where they get different wristbands and wait indoors (at least this is my understanding) until the show.
