>do I take up wing-chun?
That's for women and men who do refined sparring, not for street
Effective but even in 3rd world shitholes there's rules and "honor" in non-economical aggressions/brawling, the moment you do the jewish fist and gauge an eye with your thumbs, kick someone in the balls or in the ground it will be the moment everyone will jump you for being a faggot.
>boxing plus sambo?
Sounds good but i would up the game to Kickboxing and some grappling, which practically is military Muay Thai (Muay Boran) the problem with actual MT is that it demands your nerves to be busted and tons of shin conditioning which takes some time, normal KB is more effective to learn in quick time but lacks some grappling that MT has, if you combine it with Sambo then i think it's quite integral.
>Just learn to carry legal weapons and fuck bare-handed combat ideology?
More like learn to carry legal (or ilegal if no one notices) weapons and
learn bare-handed combat, you still fight under a system when carrying a knife, a man who knows when to cut, kick and grapple you is more dangerous than a man you know will use the knife only.
Savate, both french and dutch or at least the complete ones that are actually that, show how to fight with knife, hard stick/baton and kickbox so if you can somehow find a gym or academy that shows that then go ahead, gyms that teach kickbox or muay thai rarely go into the weapons systems.
Also stamina/cardio is extremely important, either to run a lot if caught by many slowfags or to withstand more time on alert in a fight, most winners in street brawls are those who are the less gassed and thus the more alert to strike the good hit or simply withstand the ordeal.
Brawling for respect/things not related to getting mugged are also ironically an opportunity to get friends as many end up appreciating your actions there, taunting and hitting from the back will end up making many bitter while being respectful (not striking in the ground and letting him get up, not hitting when opponent is stumbling, etc, being silent and not looking someone down) will often make the loser or the receiving party to be more considerate. It's dumb but it happens a lot. A small gangbanger who 1v1 you will not grow that much resentment if you don't poke fun at him if you beat him, of course this all applies to kin, if you are brawling ghetto niggers who don't care at all about the folk then yeah go ahead and stomp his head if you can or go Bronson and pretend to be innocent only to bait them into a dark corner and shoot them several times.
