Oh, and another thing to watch out for with KM (or any other "popular" martial art) is that when they explode in popularity like this, you have to be real careful of the quality of the instructor. (Not talking about the guy in this thread, speaking generally here) they spread so fast that you can have a guy with a year's experience opening his own school.
I mentioned to a buddy beforehand that I was a little apprehensive about trying this new KM school, because there was no pedigree on his website, and sure enough, when I got there and asked him... he had been at it about a year!! Did that qualify him to show me the basics and give me a good workout, (when I went in with zero expectations other than to get a good workout in) I think so.... but did it qualify him to open his own school (with a big-name affiliation) I dunno. I was a little alarmed by a lot of students in there that thought this guy was Bruce Lee incarnate or something... I saw bigger macho egos in KM than I have ever seen in my BJJ school (I think that's because you quickly learn how much you don't know in a hands-on MA like BJJ
as opposed to what you THINK you know in a TMA)
In this guy's defence, he did have a very high-ranking co-instructor that was going to start teaching as soon as his obligation at another school was up, so the school was probably goign to measure up eventually, but still...
Anyway, do a background check before you sign the contract! Again, I'm not picking on KM specifically here, this applies to all popular MAs... KM, BJJ, MT, etc. I've seen BJJ academies here in the Austin area being taught by blue/purple belts! And just because they have the belt, you should still look at their competition history. The guy running the Gracie academy here in Austin went from purple to brown to black in just over a year (while not actively training under a black belt) ... rrrrriiiiigggghhhhttttttt. (Not knocking the guy necessarily, he may genuinely deserve a BB, but that sounds awfully fast to me!!)
