I love the PT2's and they are my daily drivers, but I re-wick mine with Peaches & Cream cotton yarn. Stock coils, just re-wicked with cotton and no more burnt taste ever. I pre boil the yarn in distilled water prior to use. It is a perfect fit for the stock coils, easy to feed through if you wind a little bit of Teflon tape on the end ( this may take some practice) but it is really worth the effort. A plus is that if you pull the old wick, dry burn the coil, rinse it out, and re-wick at every fill or every other fill depending on how much your juice tends to gunk up you coils, they will last a very long time. It took me a little while and some practice to get the hang of this, and it sounds more complicated than it really is. I vape a lot, and toss like one or two coils a month now doing this routine with my Protanks.
P.S. You can practice on the old coils first, hopefully you have saved some of them...
