Re: Question about bigger hookahs
Well you are using bowls that generally don't always produce amazing smoke unless you get very good with them. You may as well be very good with them if you are using Mod bowls and having enjoyable sessions with Chinese hookahs!
Based on what you have described, you already know what to do. A taller hookah doesn't mean you need to change your bowl method- BUT, a KM bore is very wide, the pull will be different than your Chinese rigs and the tobacco will burn a little faster because you will be pulling more air through at a quicker speed.
So try out the way you have been doing it do far, chances are the difference will not be that great, and you will have a great session!
One thing I can recommend is a Vortex or Phunnel, Phunnel is my favorite!
