99% of combat is shock and awe, this has buckets of it. I tried it for awhile, not really my thing, but it is fun and awesome. If you want to be able to fight take some form of Tae Kwon Do then anything else. It is the base and you can jump into practically anything after that.
Basically:
TKD=Raw, fight, kill, Win+self confidence you could win in a real fight.
Capoeria=Fun community, needs muscle to do crazy stuff and get coordination and balance, but is crazy cool.
The two though, are COMPLETE opposites (I speak from experience).
