u guys are dumb. a flair is still 540 degrees of rotation. whether u combine a 5 with a backflip, or you do a backflip then a 180(a backflip is 360 degrees of rotation + 180 = 540).
in the halfpipe a flair is more of a rodeo 5, or flatspin, then it is on a quarter pipe too. some people, like jon olsson for instance, does more of a flatspin in the pipe, sorta a lincoln with a 180. but if u see dumont do one on a qaurter pipe its the same trick, he just does more of a backflip to 180, still a rotation of 5 degrees.
technically a flair is a rodeo 5, whether u like it or not.
