Okay so it'll be February 26th. No inverts are allowed. Last big air of the season.
On the subject, sack up and send it. It might feel corked at first, but the reality might be way different - you might be almost completely inverted or you might just have your head tilted and the 7 will be a normal one. It took around 100 attempts for me, as I thought it was corked and was claiming it but the reality was that my head was just tilted and I was doing really stupid looking almost-normal 7s and 9s. Ask somebody to take a video or just tell you how it looks like. Eventually you'll get it, good luck!
