Same here, Im tall and skinny (6'3" and 160lb), if your weight matches your height, you don't look goofy. Unfortunately thats not the case haha.
But yes, it does matter, it's hard to have good style in the air when youre really tall. Just harder to tuck your longass legs in and bend your knees as much, etc.
6 - 3 here...
big turns, big drops and big skis needed !!
