Might be just me, but I don't remember seeing that much hand-waving in "current" snowboarding vids. It also seems to me that the stances are a lot narrower on this one. Some of the riders actually seem to be going a bit knock-kneed to get themselves lower. Reason I'm concerned is because I've noticed when I'm jumping the 20' on Seymour I tend to bring my back arm up over my head. Am I fighting rotation, or am I unbalanced because I'm standing up too tall?
Coffee is your friend. Everyone else is an acquaintance.
back in these days there were really no snowboarding boots. we wore sorels and destroyed ankles for it. the knock-kneed stance is mostly because with those boots and the shittiest of bindings you had pretty much no ankle support. that and dudes running tiny forward racing stances.
i'm not sure what you are doing donutz but grab your board - it will give you something to do with your hand and help you keep your balance in the air.
you probably are standing too tall if your standing tall in the air at all... you wanna be tucked
