Sambo has its spot...i do like the tossing and rolling to a subission. Its basically a mix between judo and jitz. In a ring Sambo can be the shit. But, how many street fights to you hip toss someone to the ground and shoot for a triangle or heel hook? lol....know what i mean? The Krav Maga is hard as hell to learn unless you are prepared to get the shit kicked out of you. If you find a studio or gym that teaches it without getting your ass kicked, its not the real form. I know the basics of it which is use everything you can to defeat your opponent or, to disable someone with a weapon very quickly Which includes eye gauging, kicking, tossing, spitting, whatever it takes. Basically if you get really good at it, no matter what size you are you dont have to worry about anyone fucking around with you. lol!
