so many damn choices...lol 
right now, i've got my hippo airflow control screwed on, and my stainless li'l mamma tank. earlier, i had the pro vex rocking, but i noticed my o ring was getting a bit loose on the bottom, so it's out of comission until i get replacements (and colored tubes) from vaperfexion. i also have a couple of kir fanis tanks (the angel and the prive veradero), a few phiniacs, an ibtanked, a couple of regular smok tanks, etc., and so on. there is no limit to what you can put on top as the "crown". enjoy it-it's a great tool.
