Hi, and welcome. I'd say that you can use pretty much any type of wick. It depends more on what type of wax you are using, fragrance load, colour etc. Everyone will probably tell you to test, test, and ummm, test. Find a type of wick that works for you. Personally, I started out with unprimed zinc core, then tried a plain flat braid, then moved onto primed LX, CD, HTP etc. I now prefer to use a wick pin and insert the wick afterward. I just found it quicker with less fussing around, and definitely less leaks! Boyd.
