Choose the event Ladies' Giant Slalom. This event requires you to navigate a course bound by flag checkpoints. Holding down the RT at almost ALL times will help here. Stay as close as you can to gates on turns, and be sure not to miss any gates, as the speed penalty is costly. Like the Ladies' slalom, this event is the cumulative time of TWO runs on the course.
