Bigspin flip.
I tried a couple months ago - kind of dicking around - to get fakie big flips. I could never even really get close; I had no control over them.
Then, maybe a month ago, I tried them again, and I got one within, maybe, 15 tries. I realized when I first started trying them, I was throwing them WAY too hard. If you just put a little flick into it, it'll spin; it's such a gentle trick.
Then a couple weeks ago, I said fuck it, and just tried a regular big flip. I was surprised how simple they were. You have to put a little more effort into getting it to spin and it's harder to spot your landing, but it's really not too difficult.
