I agree with Fatty. The footage is rather impressive.
What is this "typical french coolness"??? first time I hear this.
The dude is actually saying that the timing was the hard thing to get, and will be working on a system that prevent the kiters to get a huge boost when the surfer let go of the rope..
But I am French too, so I might be a little biased on this one

Cheers.
