I have a Phoenix rba coming in the mail and would like to start getting ideas for making coils. I found a link to a youtube video for the ZEUS!!! coils that looked awesome, I think I'm going to try that dual coil build first it looks very promising for vapor production. I also have been reading that silica wick is not the best thing to use because it breaks down and sends silica splinters to our lungs, I saw some people using cotton yarn as their wicks, any opinions on the yarn versus silica for wicking would be great as well.
