Re: 2000$ to spend on a new hookah
It comes down to personal preference. I have a 38" KM and to be honest, it is a little big. It makes cleaning a little tougher.
All KM's will smoke very similar. If I were to buy another KM, I'd shoot for something in the 30-34" range.
For 5 people, a small phunnel bowl will be plenty.
