I've been following the admin here david (i think owner of this site as well) for a very long time on youtube. The guy is very good at what he does and even called SFOR yesterday morning. What is really crazy is that he called SFOR well before any of us really started talking about it at .0004

As far as chart videos go david is way better than clay.
