Hi and welcome, @JefferyJ - I'm going to move this post over to the section of the forum where we talk about tanks - hopefully you'll get some more views and responses there...
Good deal with the Sigelei, I love those mods - is yours the standard 150 or the 150 TC? That may help people suggest coils and settings, though I don't have a Tobeco (I think that's the manufacturer) Super Tank myself.
Also would like some recommendations. I have the Sig 150W TC with an Arctic tank and despise the .2 Horizon BTDC double coils so far. I ordered the smok tf4 with some quad coils. I'll let you know how things turn out.
