I like mint a lot. That is usually what my boys and I smoke. But my preferred flavors would have to be from the Starbuzz brand: Blue Mist (blueberry) and Tangerine Dream (tangerine). I mix them into the same bowl and they just are a perfect combination. Otherwise, mint.
It's not as bad as you think depending on what brand you get. Don't go cheap, thats where you get fucked over. Try buying american tobacco products, and stay away from the fruity arab boxes. (i.e. fruit punch, pina colada, apple, etc)
Watermelon and apple are truly disgusting flavors. They hit really harsh in the beginning, and the flavors just die down while you actually start getting them to burn.
Dude, I've been smoking hookah since you were like 10 years old, I know all there is to that kind of stuff. It's not as bad as smoking cigarettes. Cigarettes have all the harsh chemicals in them to keep their flavor and boldness, whilst shish has pure molasses syrup that can actually expire. Its more natural, and lesser harm to the lungs since you are inhaling water vapor.
