I'm not sure about how he runs a class, but I do know he has some really good schools and blackbelts. All I can say from my personal experience is that the one year that I went to the Arnolds when Relson still ran it was the worst big tournament I have ever been to. The tourney was supposed to start at around 10:00 a.m. and I don't think Relson or his guys got there til 4:00. Matches were still running after midnight. Many teams were also starting to boycott the Arnolds. That just kind of skews my view of him.
