Okay so it'll be February 26th. No inverts are allowed. Last big air of the season.
-Feels-
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!
