All I can say is WOW

I should have tried one before jumping straight into rda's. I took a hit off of a friend's and the draw was way too tight for me compared with my drilled out Patriot. Crazy how just a few weeks ago I couldn't even hit an rda or rba without coughing.

Still want to try one though since dripping can be a bit inconvenient.

Get a Kayfun 3.1. When the adjustable airflow is fully opened it's the most airy version of the Kayfun.

It's about equal in airflow to my Trident V2 using the largest single hole setting.

you may also try the Russian 91% which is the same as the Kaifun Lite but with Air Flow Control,

Or you could get a Kayfun Lite Plus which is the same as the Kayfun Lite but with Air Flow Control.

Or the Kayfun 3.1 which not only has air flow control, but also has a catch tank below the coils to catch excess juices so they don't go down the air holes, and it also comes with an adapter that will let you use any 510 drip tip with it.

Just got a Kayfun Lite myself. Nothing crazy.....1.6 ohm build....30ga...cotton wick..and all I can say is...WOW. My rebuilt protank heads with cotton were good but this is another game entirely!
