Yeah, I practice that for 2 years now. Not sure about my best thing, atm I want to nail one kong to precision, I always land it one foot for some reason, although I do it with almost no bending knees. Well, I should nail it very soon. It's 2 walls on the same level with a gap between them, the distance between them is around 1.5 meter.
Btw dear sir traceur, flips are NOT parkour, keep that in mind
