Everyone has a favorite leg kick so find the one most suited to you
and use it. Then keep using it until it is perfect and has become
sub-conscious. You should use only a few techniques and leave the
rest for fun. In a real situation you have to be very sure that your two
or three techniques will work. Leave out all of the fancy leg sweeps
etc, they might work in the classroom but in the street it’s a different
story. Kick to the legs and you will be all right.
