Can you do them effectively with both the left and right leg?Yes, I've got a few combos that I can to reasonably. And of course some combos work with both back kick, turning side kick or spinning wheel, depending on target and opponent stance. The main purpose of my spinning wheel kick is the legs. Wheel kick to the liver is very hight change of getting the leg trapped (and that is bad for my back). Very few will catch a leg kick unless it's a grappler of course, then any limb is an opportunity
