There's no hard and fast rules regarding anything. If it works for you then it works for you.Slightly off topic, but I found that the only way to get the best flavour is airflow wide open. Even slightly closed the flavour dissapears. Am I crazy? From everything I've read, less airflow is supposed to mean better flavour? Apologies for going off topic but the moment I find someone who has experience with the Drag x I gotta ask
I personally use all my gear with airflow wide open, I prefer it that way. My wife uses hers closed off a bit.
