Than et al. have great points, especially about starting wide so that you can get wide. The other thing to consider is your body position through the turn. @ShaneH pointed out your body position through the gates. Look at how that problem is exacerbated by the time you get to 1 ball and watch the path of your right shoulder going into and around 1 ball. There is little counter rotation so that the problem that @ShaneH points out only gets worse and not corrected, leaving you short on leverage and ultimately short on angle. I personally find myself skiing one pass technically very well and then cutting the rope and everything flys out the window, the technique goes to hell in a handbasket. I have to remind myself, that yes, technique becomes more important with a shorter rope. Sometimes it takes a less than gentle reminder from someone in the boat, but then, the next pass becomes much easier.
