Low-Cal Summer Cocktails

In an effort to drink responsibly (read: healthy), a girlfriend and I have mixed vodka and Crystal Light for years. Recently I noticed they caught on to our concoction and created mocktails. So this past weekend we tried out the Pomtini. I have to say, it didn't taste much different than the other fruity flavors we've used before...perhaps the margarita flavor will stand out a little more. Either way - I highly suggest! Have you tried any of the mocktail flavors?
