I've always just kind of used whatever wicking material I picked up first I have the usual cotton bacon the Muji I have unicorn hair I've tried Firebolt whatever the hell that stuff Geekvape uses and I can honestly say the other day I needed free shipping for my Amazon order so I decided to add 13 feets cotton. It is the easiest to use cotton that I have ever used in my life it even beats out the shoelace aglet Style. The full width of the thing is perfect for mesh and I break it in half for most of my other coils you know give or take a little bit. I love the way it feels it doesn't feel squeaky I hate that feeling it makes my teeth hurt I love the way it wicks I love everything about it. I never really noticed a lot of taste difference between the Cotton's that reigns true here but if anyone is on the fence about picking up a bag of $5 cotton called 13 feets on Amazon just buy it. Now I wouldn't buy it if I had to pay for shipping but that's just because I'm cheap.. it's well worth the amount of money that would be like 13 14 bucks
