I have the utmost respect for Eniz' longevity and his no bullshit approach, as mentioned by fellow commenters down here loved the hpx+xtreme and the overall filming on this, props to Fabien!
Seeing those spots live makes this part even more incredible. Many spots are so rough and hard. For example, you may not see it from the video but the roof in 03:04 is so low that you can easily hit your head to it by mistake.
