I don't know how any name other than Henrik Harlaut could even be mentioned.  Arguably he's already too "big" to be mentioned, but there's no doubt in my mind that this kid could produce this next year's best segment(s) and win any/every slopestyle event he enters this year.
  Come on, he stole the show from both T-Hall and Sammy in the NZ edits...
  For a slightly less obvious choice...LJJJ
