I wick differently than he does, but he can show you the coil. The idea he shows is right on par with the cotton being bow tied around, But I put just enough to not add any extra. and he shows you pressing it against the walls and that's what I do as well. You want to cover as much surface area on the coil as possible tight, but not to tight just snug enough, then when done look at the top and cotton blocking the top of the coil move it out, also look down the coil see if there is cotton coming from the bottom covering the air hole, and you can just get a small screw driver in side the coil twist it around to clear it. So its just air hole directly up the coil and the coil shoots the vape directly up the kayfun chimeny, some juices like super fruity like citrus stuff going to hit your throat like a truck. Anything around 1.3 - 1.5 or so, is what I do in ohmz
