I used to smoke hookah, but gave it up about a year ago since my girlfriend can't be around smoke.
I had two: a little mini travel hookah that was clear purple like the old Gameboy Color almost, and a big blue one with some fancy gold swirls painted on.
As far as flavors, I would only smoke really fruity flavors with my favorites being apple and peach. There was a hookah bar in my hometown though that had some of the best mixed flavors you'll ever see, making so many sweet combinations. My favorite they made mixed peach, mango, raspberry, blueberry, and a hint of orange.
