How do you straight line a face? A good SFD (straight F^8kin down) is the ultimate way to end your run. Just put all the stoke in those last seconds. But the better SFD's have even more advantages. You basicly fly over everything and if you hit anything, it only ends up in a vertical damage in your P-tex. And connoisseurs know that vertical damage is way better than horizontal damage ending at the edges. The second advantage of straight lining is that you can keep an eye on what's in front of you. Speed checks can be dangerous ;-). If you're not straight lining, your board can start to bite or the sluff can overtake you. SFD it is!
