So i've been vaping the "slim" 2mm wick for a couple days now and so far I like it. The 1st coil I set up with it was a 5/64" tight wrap mini coil and it slid right in very easily and vaped pretty good. It seemed to gunk up kinda quick so I did a dry burn and that is when it went really wrong on me. I tried vaping it for a few hours, but it just wouldn't keep up and got quite a few dry hits. It just seemed to take forever to absorb any liquid after the dry burn and it even looked like it had a burnt spots on it at the ends of where the coils were. The dry hits on it aren't in the same ball park as cotton, but nasty to say the least. Grew very tired and frustrated and decided to re-do the coil again since it was suggested that it would work with a micro coil. Whipped up a 1/16" .9Ω coil and that is where it got interesting. My old eyes and shaky hands finally got a piece threaded, (you have to screw it into the coil), in it after about 15-20 minutes, but once it was in there it slid back and forth rather easily. It does have a very clean taste to it right from the 1st hit, unlike cotton, and vapes very well. The jury is still out as to the next time I have to do a dry burn to clean the coil again. It doesn't seem to have gunked up as fast with the micro vs. the mini coil though. Again, we will see how it does for a few more days and what it is like after a cleaning and dry burn. Hopefully it will go better with the next one...
