I've gone to three BJJ school's in LA for the beginner intro class. Since I don't have any experience in BJJ I wanted to ask what are your opinions on the quality of instruction and quality of students at the following schools: Rickson's Academy, Rey Diogo's Academy, and John Machado's Academy. Looking through each academy's webpage it looks like they are all extremely well qualified. I'm looking for a "no nonsense" and hard working school and it was hard for me to get much of an impression after just one into class. Any advice would be greatly appreciated. Also, Torrance and the Valley are too far for me to commute. Many thanks.
