What is your favorite flavor of sparkling water or flavored water?

There was this one brand that I could only find at 7-11. The flavor was Kiwi Strawberry and it was really good. I would buy about 3 a week. About a month ago I went in to get one and they told me they didn't sell it anymore. I was crushed. Furthermore, I was more upset because I couldn't (nor can I still) remember the brand of water that it was to even attempt to locate it. Oh well. What's your favorite flavor?
