Hello and welcome to PotV. I have pretty much used only RTAs for the last 3 years. I'm now using the Innokin ARES 2 & the Ares 2 LE. Very easy build deck, actually, the easiest i have ever come across. I use 26ga SS316L for my coils. I also DIY my own eJuice and I'm getting great flavor at 12 watts on a ,6 ohm coil vaping my DIY Whipped Mango. Congratulations on not smoking.
