I think I'd go with Dane Brady's "I like It Here Inside My Mind" part. I was tempted to write about parts that influenced me when I was younger like JJ in Mindfield, Wastell in Kronichles, or Antwuan in Baker 3, but this part just stands out so much from anything else. I still have a lot of fun watching it. It's full of really great skating and the crazy "circus" tricks are done without coming off as contrived or outrageous.
Come to think of it, a big reason I like JJ's Mindfield part is for the switch wallie/wallride tricks, and Dane does some insane ones in this video (sw wallie fs 360?). The edit is wonderful too, fell in love with the song immediately.
