Brisk makes a strawberry lemon that I'm quite fond of. Otherwise I enjoy a good cherry Dr. Pepper. After a kidney stone 2 years ago (almost to the day in fact) I learned to also love Ocean Spray's Cran-Grape juice.
Had a room-mate and we liked to mix Orange Crush with a Parrot Bay Pineapple flavor, but it was rarely. Just don't care for the prices, especially when I enjoy the taste of pop and Cran-Grape for much cheaper.
