Your right, I did not give enough information!
I want a martial art for self defense and possibly even competition, an art with no weapons, just hand to hand combat. I like the idea of Muay Thai, because it is very 'deadly' and 'brutal', and seems to be effective, but there are so many other styles out there (especially Chinese)! BJJ is great too, and from what I have seen from UFC and similar, it is a very important art to know. I LOVE them both!
I do both Muay Thai and BJJ, but I question which one I should do more, if any. If there is something better out there, I will drop muay thai and BJJ, and go for it!
Oh boy, where to start....
1) Am I safe to assume by reading this post, that you're looking for something that can be used in the ring? If so, your best bets are BJJ, wrestling, boxing, MT.
2) If you're looking for something that would make you more well rounded, you'll need to focus on all ranges of fighting and that will include weapons.
3) MT is "deadly and brutal"? Yup, and so is Kajukenbo, Kenpo, Silat, TKD, and so on and so on and so on. My point....dont fall into the deadly and brutal stuff. Anything has the potential to be those things.
