Try the Dew flavors, chocolate fudge brownie, chocolate strawberry, any of the milkshakes (Shamrock Shake is a crowd favorite). Anti-Venom, Cinnamon Red Hot for candy flavors. White chocolate tobacco and RY4 are both great. Cinnamon Roll, Boysenberry Pancakes, Mocha, Espresso, Caramel Latte.
I could go on and on...I've tried nearly every flavor and haven't been disappointed.
