I used to have fun doing step off tricks back in the day, but I tried to keep it to one foot step downs. A little different than what you're doing, but I would step off with my left foot (I skate goofy), flip the board over casper with my right and sweep my right leg around spinning the board 360 and back from casper, and turn my body 180. it was like a no comply impossible half flip or some shit. I did try to do them without the step down but I would always wreck myself. I don't know that there was a name for it, but my friends coined it a krypton flip. this was me just trying some wacky shit, trying to be like Rodney or Mike V, and failing for the most part. but I did end up being able to do slow rolling casper stall spins or whatever those are called.

but I dig what you're doing, man. really cool in my book.
