Thanks for all the very useful comments, I'll definitely read the articles, Bob. Suprtrkr all the mods behavior was solved when I wicked properly. It amuses me how my wicking remained sloppy after years of vaping, using RBAs. Opinionated, I used Japanese cotton up to this point, but I feel there is not much difference between that and cotton bacon. The only difference for me is that its easier to take off parts from cotton bacon, however measuring is an issue, where with Japanese cotton, I could just cut off a proper size strip, and it was sorted. I will probably change back to Japanese cotton. I have read disturbing articles about Rayon, and it is not available where I live, so I guess I'll skip it, but if I can get hold of some through a friend of mine, I'll definitely give it a try!
