I've been a big fan of Koh gen Do for a long time, 80 large pads from Amazon for around $12 and that's enough to last you 1-2 years depending on
vaping style. I just picked up Cotton Bacon Prime and I'm very impressed, it's worth a try.
Rayon, I can't stand it. They say it has no flavor but I can taste it. It gives me a dry scratchy
throat and if you get a dry hit it's the most vomit inducing experience ever. Before the Rayon Zealots jump all over me yes I gave it a good try, yes I did it right and yes I used the right Rayon (Sally's).
Bottom line is try various wicking material then settle on what works for you.
