I have had just about everything under the sun from Provari 3 years ago with I clear 30 tanks, to four nine with plume vale and all the crazy coils you can think of. Right now I have an ipv2 that I have been running a Tobh with 24 Guage 7 wrap dual micro coils. But just 2 days ago got the Atlantis sub ohm and got to save after dripping for 2 years, I am loving this tank. (Didn't think I would say that but there it is)
