Hi, I have been a longtime user of sub ohm tanks and felt the need to move on to an RTA. Currently, I am using an Eleaf Istick Pico and a Wismec Reuleaux RX 2/3 mod. I have purchased a Serpent Mini 22mm and a Geekvape Ammit 22 RTA, both of them single coil RTAs. I would like to ask you guys to give me a good suggestion for setups for these 2. Basically just need around 0.3 to 0.7 ohm builds using plain Kanthal A1 or Clapton. Coil diameter and wire gauge info for these models will be a great deal of help for a first time builder Thank you.
