Lung hits are always going to give you better vapor production, especially with increased airflow. If you prefer mouth to lung inhales you need 2 things from an rda, the ability to restrict airflow to get a tighter draw and a small chamber.Same here! I had no interest either. Just this past Wednesday I was in the local shop and got talked into trying it. Bought a Quasar dripper and built a coil at about .85 ohms and WOW! Flavor and cloud like never before. One caveat I've noticed is I must lung hit in order to get the expected result. Mouth hits produce little vapor but good flavor. Im sure other devices and coil setups would change that which produces reason for this wonderful forum.
