as far as wicks, I use sterile cotton balls from CVS...3 bucks for a many year supply...im still using the same cotton ball as when I started, weeks ago...so it lasts a very long time, depending on how much you vape (I have been srsly chain vaping a ton lately).
I use a very small amount, its two rice grains worth if that, and roll it until its as thin as a pin, thread it thru my coil and then prime it with juice.
as far as Kanthal, it depends on what kind of coil you want to do, I got some 30 gauge but maybe should have gotten 32.
The Diamond Coil - YouTube
this is a newly found video from RiP Trippers about making the Diamond Coil and I really liked it...but I am using Kanger mini protank IIs and it probably would not fit in my head, its pretty large - I am also using a Kanger EVOD VV so I dont have a way to test my coils resistance either....sooo...I have to wait till I get an RDA + some nice mod.
but I really liked the video.
