Before using braided Nextel, you need to download the spec sheet, and understand the "conditioning" process. It needs to be heated to burn off the sizing coating they put on it as part of the manufacturing process. It is not something you want to
vape unless you burn that sizing off, and by 3M's specs, it takes some pretty high temperatures to do it correctly. Unless you know someone with a ceramics kiln, or you are willing to heat it with a torch for an hour or more, this stuff is not something you can use right off the spool.
I've looked into it myself, and decided it wasn't going to be worth the trouble. If I was still in grad school (where I had friends who were grad students in ceramics, and could have kiln-treated it for me) I would have gotten a 100 ft spool an "gone vendor". But it's just a pain in the .... to process with a torch in small amounts.
All that said, it DOES vape very clean and smooth. Flavor is great, and vapor production is thick. It's the best stuff I've found, short of stainless mesh for clean flavors, and aside from the initial treatment issues, it's as easy to use s silica wick, and MUCH more durable if properly conditioned...
