well krav maga was made for real life situations and not for sport. from what u say u want, krav maga is more what u are describing than wing chun. wing chun is pretty much just striking. im not sure if grav maga is well rounded, but it should be if it was made for real life. also, i think u would like what kajukenbo has to offer. it pretty much sounds like what u are talking about. kajukenbo is for street fighting. 2 of my buddies take kajukenbo and ive seen their classes, its tough. they grapple, box, kick, do weapons training, all kinds of shit. from what ive heard about krav maga, it sounds similar to kajukenbo, although krav maga takes fighting terrorsts and being held hostage and that kinda thing into account in its training i think.
my friends train here
