turpin's not wrong
a misty is NOT simply a front flip 180, thats a barani
think of a misty as going up to a picnic table while running, then dropping one shoulder and rolling along it
they can be done in different styles of course, but in certain ways, they are exactly the same as an overflip
it really is the same thing
and in the end, it really doesnt matter, its not a huge deal, ski tricks just arent that black and white, in comparison to say, a kickflip and a varial
oh and spinning and flipping backwards does not mean its corked
its often a d spin, or just a really shitty full
that gets messed up often too
