Retail staff rarely ask about airflow tuning directly, but their questions almost always lead back to it.
Why airflow tuning matters on the Nex 4

Where two suppliers look identical on price, airflow tuning is usually the variable that separates them over a full year.
Open airflow serves direct lung users who prioritise vapour volume.
