I have to be real honest, I am really loving the Nuun. It is my favorite new product and will be in the bag for a long time. I had the banana flavor as I drove to the course, and it was much better this time around (maybe had too much water last time) and I had the fruit punch on the course. The fruit punch is far and away my favorite flavor thus far, with tri-berry coming in second. I have yet to open the tropical, but I am heading to the range tomorrow and will give those a run.
