This greatly varies on the stems. The tighter stems allow little airflow but the loose fitting ones are awesome! I have 6 stems and most fit tight, but a couple (my originals) are nice and loose and the airflow is really good, albeit not even close to my eq. I still have no chipping/flaking but I have almost exclusively been using a tighter stem. I wonder if by using the loose ones, and me kinda wiggling/manipulating the bowl while looser, might be causing stress on the ceramic coating. No worries, my present solo continues to shine with no flaking and no smell whatsoever.
I must also mention that I ALWAYS use screens and that will definitely help airflow too. A finer ground and loose fill with a screen and loose fitting stem should give you satisfying airflow for a portable. I find the airflow too restricted for vapor bonging, but that's what the eq is for.

The air flow on this thing really needs to be fixed. How are others working the air flow? I mean I can't seem to get nearly any suction at all? I have found that 2 or 3 setting works good because of how slow I have to draw the thing. I think it would work much better if I could draw the hot air more throughally through the thing. Has anyone had a breakthrough with air flow yet?
