I like Judo tosses they don't use them to much in MMA though but for though striking would fake a shooting in for the legs and as you do throw a haymaker to the opponents jaw it hits most of the time and the opponent can't do much because they will try to catch you and sprawl and take the full force of the blow. I've seen dan henderson knock some guys out with it in pride. Favorite grappling technique not sure really maybe rear naked choke just very easy to get to me.
