I have been using Grey Fox for nearly two years so let me start by sharing my experience of the new version. First of all more of the current powder is absorbed into the water so there is less residue in your glass. There wasn't a lot of residue with the previous version but it is now almost zero. Second, the original flavour was fine but this new Pineapple and Peach is another step up. Good job! There have been so many positive benefits for me from using Grey Fox daily. More energy, faster recovery after exercise, I am more alert and can sustain my focus for longer. All of this has also led to a more positive mindset. I would recommend that you give it a try - nothing to lose but so much to potentially gain!
