Re: Hookah Heights
I have a 19" and it smokes great. I think large ones are nice (27 inches and up)because they have a longer stem witch holds more smoke, and helps cool the smoke before it gets to the water.
As I've figured out with my hookah is that the base is small so its tough to get the amount of ice I want to fit in. With a large hookah you'll have more room to breath and play around with your sessions.
All in all its your call. keep into consideration that larger hookahs are a lot tougher to handle and travel with.
