I have the Subtank and Subtank Mini and Lemo Drop and Atlantis and Russian 91 and Kayfun and, and, and, and..............Anyway, Drop for flavor, Mini for reliability(stock coil) when I'm out running around town, Regular Subtank when I'm at home because i don't have to refill the tank as much. Russian, Kayfun, and Atlantis have been sitting collecting dust for a while now. My biggest boogaboo now is this back and forth business between Kanthal and Ni200 coil builds....can't decide which i like better but leaning toward sticking with Kanthal, plus i'm afraid that one of these days i am going to forget which tank i have the NI200 build in and fire it on the wrong device. That and the temp protection thing with NI200 builds is kind of a pain in the ..., I think. Haven't tried the Goblin yet, hopefully soon.
