One drill I can suggest is to get into the perfect body position that @mwetskier is suggesting when you pull out at the end of the lake. At this point in the pass, you can focus solely on body position and the feel of the ski, with no distraction from buoys. Look down to see where the water breaks on the ski, and glide on your front foot until you sink. NO BACK FOOT AT ALL! Get some video of yourself doing this as well as feedback from the boat. Make this a habit every time you drop. It will help build a foundation for this body position when you pull out for the gates. @Ibskiing and @SheSkisStrong - do not give up, this is a problem for most skiers and once you break through, you will find the pure joy of carving a clean, fast turn.
