The reverse or sweep kick is seldom used in JKD because, against someone in the same stance as you,the lead hand is always protecting the face. Second the kick is delivered high and is apt to be caught against an experienced fighter. Third the kick is not powerful enough to knock your opponent down.(Lee & Uyahara vol 3 1990)
Another problem with the reverse kick is that once you get your heel out there and try to spin around you're to vulnerable to counterattack.(Little vol 3 1997)
