I just reached 500 subscribers on youtube, so to thank you all, I made a small vid with some old unused clips and some newer flatland clips 
enjoy:
Thanks for the reward. I love watching you ride. You got me wanting an Impact Gravity really bad.
Mark.
thats a Great video, and some awesome riding!!
That drop at the end!
Do you ever have ankle or knee trouble?
the drop at the end is quite big, but its not hard… the landing was really soft! I’ve done drops from 2m who felt a lot harder than this drop (from ±4m?)! 
I only have problems with my ankle if I land wrong, but not specially from big drops… same for my knees
and thx for the comment
