Honestly, it sounds like you know what you're doing wrong, and what you need to do to fix the problem. Are you landing in the flats, or on the downslope. I found that coming in a little slower to land on the downslope of the other wake makes HSFS 180s much easier. Concentrate on getting up and over your toes and edging away from the boat on your TS edge. Keep trying, you'll get it!
