1. Simple builds - it does not have huge airflow and flavor comes from balance of air and vapor, big chucking builds will just give you soup vapes.
2. Coil height - top of coils level with middle of top post holes, any higher and the coils will cut down the airflow even more ...once again giving you soup.
3. Wicking, whatever you do that works in other tanks.
Thats about it. Single coil through the middle also works well if it's still too soupy and you want to balance air/vapor a bit more on the air side.
But if you dont get any flavor use your horrible juices in it as you won't taste them...bonus!
