Almost 0,very light ones. Id like to smoke 3mgs and then switch to 0. I was smoking for like 1 year
Since you're a very light smoker, I'm afraid that the tanks you've chosen may be too much for you. I'm not sure why you only have three choices, but in case you don't, I'd recommend something much simpler to use.
Get a simple TC box mod: Eleaf 40, eVic VTC mini, Wismec Presa 75W or Pico are all decent choices and can be had for ~30 bucks if you look around for sales and deals. They all work fine in both power and TC modes.
As for tanks, the most cigalike and user friendly is the Eleaf GS Air Tank series. Get the old 1.5Ω dual coils--they work great out of the box and the load (wattage, power) is split between two coils, so if you apply 10 watts, each coil only gets 5 watts. They are really nice. The tanks come in different sizes and Eleaf also offers Ti and Ni TC coils.
I also love and use eGo One tanks--I like the megas (4.5 ml), V1 or V2, both good. Single coils, both TC (Ni and Ti) and non-TC, very easy and dependable. I recommend you throw away the included CL coils (they are garbage) and buy 1Ω CLR (rebuildable) coils. They can be used out of the box and later easily rewicked/rebuilt with any wire you want (if desired--they are ridiculously easy to rebuild).
Good luck!
