I have been out of vaping for a few years and just bought the boro device listed above. I was used to building my coils using kanthal. Now, I see so much has changed. What is the wire of choice along with cotton? I see a lot of pre made coils and am just curious as to what I should do. What ohm coils should I be using with this device, it's a 70W max. Thanks for the help.
