Personally when I compete 70% of points come from kicks to the body, I grew up in a very tough neighborhood and although I do not brag about being in 20-30 real fights I have been forced into two fights that I consider to have been for my life in both cases I was able to escape with a single kick to the leg in one the ribs in the other. I think that a leg kick is more practical than a sweep in most situations. I remember the good old days where perfect technique on anything got a full point and anything less was a half point and three points won.
