yeah, i pretty much think "ooo shit!" then land, but try to soak up that impact with a roll or something. Try if possible to avoid kneeing your chin, this hurts like a bitch and you can def knock some teeth out or cut your tongue off if you are unlucky...
Best advice is prob just let others go before you and then copy their speed if they are clearing the jump easily. I no longer am the first guy to hit a new jump, it's just not worth the risk.
