Why airflow tuning matters on the Stark 4
Restricted airflow suits mouth to lung customers moving from traditional products.
In practice the decision comes down to three numbers: unit cost, freight per unit and the realistic sell through rate for Stark 4.
Open airflow serves direct lung users who prioritise vapour volume.
