this is not progression, weren't any of you lil ones around for the acro dayzzzz, they did way crazier shit than that, they did like tip roll 9's and crazy shit. charles is just bringing back the old........but still very sick, because he is on normal length skis, not 150's like they had back in the day...but i think if the sport went this way, i would quit or not do it because i cant bend my knees like that...
