The cotton I had someone pick up for me is CareOne 100% cotton found in the baby section there. I was able to take apart several of the Smok coils used on Tumbler, Trophy, HBC, GBC, RBC, and some other tanks before the T-Series arrived but couldn't get the consistency I was looking for with some down as low as 1.7ohm on a 2ohm coil.
The Japanese cotton there comes in flat sheets rather then the fuss required to tear small pieces off of cotton balls in order to twist and shape the way the original wick was or how it will mesh with the RDA, RBA type coils.
Heating the wire either by flame or by firing dry wouldn't be any problem as far as a slight heat treat for prepping it. Most likely just a half dozen burst fires dry would suffice without the need for using a lighter or torch. The old Zippo lighter I would rather leave in the "Forget Me Forever" archive!
What most don't know is that the US is the one who originally supplied the Japanese Textile industry with cotton in the early 1900s before the first World War came along. There's also some comparisons made between domestic and Japanese cotton as far as cloud making as well as the taste comparisons. I came across one discussion where someone was saying that Agent Orange is still in use once the growing season is over on domestic grown cotton? I would think more in the lines of bleached or prewashed at least to be labeled sterile cotton with some packaging while most I ever see is packaged simply with 100% in print.
The Atlantis is a great one! Dude and finding a bargain price that isn't already sold out will be a challenge at this point!
