What wax issues? I hope not mine. I mix a few to make my own blend. I have a lot of experience with many types of wicks. (performa, hemp, lx, rrd, square braid, premier, cd, csn, cdn, htp, paper, zinc) I typically gravitate towards HTP wicks, but I get tired of the curling posture. I've tried some of the cored wicks, but the ones from Peak were the best I've tried. I'm even struggling with retesting my HTP scents too. Not all HTPs are created equal. I found a supplier that has the same manufacturer of HTPs that Peak did, but they still seem to burn a little different.
