I quit smoking with a kayfun lite and then moved over to RDAs. I love my RDAs because I find I get better flavour and vapor from them, the main reason I think is because I like a fairly airy draw. Ever since my move from RTAs I find my kayfun unbearable to use. What I would like is a tank I can use on the go with as much airflow as possible, I think this might make tanks bearable again.
