Re: Size of the Hookah?
A 28" hookah is the smallest I smoke on a regular basis. The occasional QT or Bambino at a friend's house can be enjoyable but there is a noticeable difference in the warmth of the smoke.
There are also very few small hookahs that are of high quality in my eyes.
The tallest hookah I have smoked is my 40" colossus. I notice no difference between it and my 32" KM regarding temperature. The draw can change with the height but not by much in the 28"-40" range. The most important factor there is the inner diameter of the stem.
