Boxing and Krav Maga
If you don't master the art of throwing a punch what's the point of the rest of the game?
And unless your gonna do actual MMA type events bjj and wrestling are kinda useless since they are based on single attacker situations
Bench
boxing will get you a broken hand and you lose 1/2 your 'weapons' in a typical street fight.
at least with muay thai you'll still have knees and elbows.... throwing a kick in a streetfight is a very bad idea 95% of the time unless you're very proficient.
low kick/leg kick allows your attacker/opponent to close the gap quickly, as it's not gonna stop him .
throw a high kick and run the risk of losing your balance and falling, or pulling a hamstring... much less it allows your attacker to close the gap again.
in a street fight where you're striking you'll want to maintain distance and when inside use the most dangerous weapons you have.. which are elbows in my opinion/experience. short elbows will rattle a guy's head much more effectively than a dirty-boxing punch, plus if you catch a bit of skull, you'll break your hand.
but in an actuall 'street fight' it's "do your worst, fast and first"... eyes, throat, and groin. you're not point fighting and there's no judges or ref's.. and as a grown man, you have no business "fighting" in the street where you'd risk losing 'honor/respect' for gouging eyes.
if you're gonna fight somebody over disrespect? it's not a fight. it's an assault... use a weapon if you wanna teach a guy a lesson.
