You need to tuck those knees when your hucking. Your flailing way to much.
That and keeping your weight forward usually are the biggest challenges. The natural tendancy is to lean back and straighten up, especially in the east because the landings are ussually tight in the trees and the thought is to try and dump speed as quick as possible when you land.
I rarely 'huck' anything these days as I'm not on the hill enough to be as confident with that aspect of skiing as I once was. 'Back in the day' when I did huck more, when I didn't stick the landings it was because of being too upright threw the air and being in the back seat when I landed.
