Hiliary, are you finding that many of these "wick charts" (not the ones that try to match jar size/wick size/wax type, but the ones that list wick properties) on the web don't give pros and cons to each wick type? They all seem to be great, but I don't always get the whole picture. That's what's got me stumped. I'm having a hard time filtering all of it b/c of this. I even have bought samples of RRD, LX, Zinc, and HTP's and tried them. What I have found so far is that the Zincs mushroom quite a bit, and sometimes the metal is exposed during burning (not very attractive). The HTP's curl as the burn, and the wick is self trimming, so two things happen. First the wick "trims" by falling into the wax in bits, so the wax is "dirty" or "sooty". Second, b/c of the curl, the flame is no longer centered, it becomes off center, and so the meltpool is off center. I tried twisting the wick as some suggested to help keep the flame centered, but did not have luck with that.
