I was never a direct-lung-hit analog smoker, never understood how people could do that, lol. So I usually vape the same way I smoked, draw into my mouth, inhale, then exhale through my mouth and nose.
I do actually take the occasional direct lung vape hit though, when I'm feeling extra manly
I have come to wrapping my wire on the wick, that way it's perfectly fit to that wick's diameter. Do be careful not to wrap it too tight though, you don't want the coil making impressions in the wick. Not too tight, not too loose. I hold coil wire about 2" away from where it is touching the wick as I wrap, makes it easier (for me) to get just the right amount of tension as I'm wrapping it up. I also try to wrap the coils as close together as possible which gives me a lot of leeway to spread them apart while working out hotspots.
