thats how i learned them, they are easy, all you do is push off the tail, just trying not to pop it, and you jump back while pushing and your front foot goes back to catch it, thats how i did my fucked up ones, and those looks like the two feet are working at the same time, i think he does it more of a power slide so he can stay in place, and how i got them is hopping back with it, i'd have to go do some to explain it better. i really wish i could get bigspins though, spent fucking WEEKS on them and they will not work.
