Yeah it's definitely out there. I have run into London twice in the last few weeks. The first was at a no gi class with Helio Soneca teaching a series from the position (?!). The second was last night with my old coach at GF Team. He put me in London and I was like "you know there is an unstoppable escape from here", but before I got the words out of my mouth he locked his guard back up... and the light went on.
