I have to disagree about Total Immersion being a waste of time for newbies. I was struggling with trying to get ready for my first sprint distance with a 1/2 mile swim. My friend and who was nationally ranked at one point told me about the technique. After just 2 weeks of honest effort, I noticed dramatic improvement. Granted, much was pure fundamentals, but the technique does work. Overall times were much the same, but I come out of the water relaxed and focused. I think it's worth checking out.
