If you new to building coils and wicking then I would suggest (and this is just my![]()
) that you first start with cotton and then try rayon which will give you more flavor, bigger nic hit and the wicks will preform and last longer. But the rayon is tricky to wick correctly in order to get the performance and full potential from it, kind of like learning to drive mom's car before you jump in a race car. There is a great thread dedicated to rayon and the folks there will be happy to get you up and running with it once your ready

The OP of that thread Jeremy, who brought rayon to us, has condensed some of the key posts from that link and some video's in his blogs here
