I found this clip fermenting on my hard drive, so I figured I would post it, and hopefully help someone out. The clip was shot as part of an experiment that is still in progress. I added a slow-motion version of the spins because (I don't mean to toot my own horn) they are a bit on the quick side.

A lot of you will notice a bit of awkwardness in the landing to running transition, this is something I've been working on lately (although parkour has been the main focus of my training recently).

Thanks in advance for your input, and if it inspires anyone to learn, you're welcome in advance. 

Yeah, that is a tree that we picked especially because of it's conduciveness for the pop-wallspin.

The most challenging pop wallspin I've done was on a vertical painted brick wall, but after a bit of work on the technique, the texture of the surface doesn't matter, because of the angle that you apply pressure to the wall from.

About getting more height, yes, you're right, I can get more.
