A way to gain speed is to gain weight!
You'll pick up speed much faster
Haha, this reminds me of something funny I heard on the mountain.
Kid (to grown-up guy): "How did you get here so fast?"
Guy: "Well, more weight = more speed"
Kid: "Wow, you must be FAAAAAA.... st"
I like riding well and in control, and I think speed will also come eventually (I'm getting there). But like others have said, good wax job, steep slope and don't turn... even if there's a tree... don't turn :P
