I try to use the same approach to gates, get wide and turn in with speed so you can build angle without load. It is a very strange feeling at first because you feel like you are turning in on slack. But that's the feeling you want, not slack but a free of boat feeling. If done properly the skier should not need to add any more load through gates, just resist the pull of the boat and maintain the angle you have. When I do this properly I feel like I am going 10mph slower into one ball and the entire pass is easier.
My wife does most of my driving and she understands that her driving entering course is just as important, if not more important, than driving in course.
