thankyou.
the first vid u showed us I said bio. he leads with his head off the jump. if u lead with your head and go forward/out/down then its a certain trick. I mean however u want to describe it, but u throw it according to each trick. but when u lead with your head like that its gotta be a front, misty, or a bio, or an overflip. but an overflip is a misty just laid out however u want, and usually inverted, or close.
the one u did on the tramp looks like a bio 5. I say that becuase u lead the trick with your head/shoulders going forward and u DO NOT go inverted. if u went inverted, then I would say misty 5.
flatspin is when u lead with your head but you drop your shoulder BACK and not down. like u were doing a rodeo but u don't go inverted. hence a flat 7 kind of looks like a rodeo 7. its like doing a backflip and either doin a fuckin backflip, or u drop yur shoulder a lil an rodeo on your back, pretend yur back is a turtle shell and u spin on it, for rod 7, or u go inverted all the way like pollard on his rodeo 5's. or u can do a d-spin 7 when u go back like that, but thats a whole other trick. and thats how u do cork too. but for the most part a rodeo 7 and flat 7 look the same to me. and cork is a different variation of that trick, and so is d-spin if u do it right. its all depends on who teaches u the trick and who u see do it. cuz then u learn it that way.
see CR johnson in Focused, and other select movies, he has some some good bio 5, 7, and 10's. peter olenick has a really good overflip, pretty much a misty 5 but he usually kind of just corks over his shoulder and doesn't really go inverted.
but where I'm from, and where I live, we call what your doin a bio.
