Old move. bboy Arthur perfected that shit. The Arthur from wanted posse and meme pas Mal crews. Not the other kid. And junior used to be able to do that move in a more twisted way in 2004 too lol
Sometimes It's hard to believe that junior has a handicap until he starts walking big inspiration for people with polio or any handicap nigga is straight amazing and heady has come along way great battle indeed
Junior's Skills are awesome, but I don't really like his style. Heady is way better for me, but I thats personal taste. They are both very good on a skill-perspective
Because his legs only weigh half as much as normal, the gravity center of his body is in a different spot than other people. Hence his moves who can't be done by people with normal legs.
