I've noticed for a long time now that there seems to be various styles of jiu-jitsu within the general sport/combat style itself. You have those who practice more of the self defense/fighting aspects, and those who practice a more tournament oriented style of jiu-jitsu. Also, you have those who are always seeking the latest triple/quadruple X guard, while others are constantly seeking to refine the basics. I could go on, but I want to see the opinions of other jiu-jitsu practitioners first.
