I saw exoskeletaL doing this conc route on destroy a long time ago. No idea how he figured it out, but I thought it was incredibly cool. I learned it and have recently started doing it in pickups. I've been wanting to get a good clip of it to record and post, but I haven't been able to until now. Granted, I'm going up against an empty FR, but I think it was a pretty good run anyway and it shows the route adequately enough.
However, this doesn't really show the true beauty of the route. You can also do the same thing but air control over to the button ramp and slide it instead. You can even potentially slide all the way to flag by going button, but it's insanely hard.
