Mine would probably be a mid-air fan I did when I did the 360 deck flip but flicked my wrist diagonally (hard to explain) and the deck did 2 360s and spread in mid-air. I caught it in my other hand and it was like a perfect fan. A-M-A-Z-I-N-G. =)
I doubt it was a perfect fan. or even 180 degress...and thats if it even happend.
