Huh. How do you describe it? Have you ever just done it and not 'thought' about it? For me the thinking part messes everything up. Do what is natural. I would have to say though, when I do it I'm farther back. Sort of like jumping a horse. Maybe you should just watch the video.. Now I'm going to have to go launch off of something and think about it.

And just remember....speed is your friend. Your butt has to definately be back- if I compressed that shock and was that far forward I would be staring at the clouds in no time! Good luck!
