Personally, I dont like the belt system. Its just a way to justify how good you are, and how much better or worse you are than everyone else. It also gives a false sence of sucurity, making kids thinking that their awesome just because they are in so and so belt. on top of that it costs money for each belt, and thats a rip off. luckily my system, muay thai doesnt use belts. like the old muay thai saying " the belt is in the ring".
