DL at high or very high wattages is all I will ever do, but when I was a smoker I was smoking MTL like most smokers are so I guess this means I can speak from true experience when it comes to lung capacity, inhalation depth, and the speed of inhalation. I never deep inhale because I am not a cloud chaser, and, I vape at 2.5mg-3mg on high VG (usually 70/30 or higher).
Right now I am vaping on a hard hitting series mech with dual Samsung 30T batteries, these are the hardest hitting batteries available to us. My RDA is the Deathwish Modz Unholy V3, this is a 28mm RDA. My coil build is .26 ohms dual coil so that's a reasonably powerful vape I guess. Yet, despite this, it isn't a hot vape. In fact I don't like hot vapes in any way at all. If you think my draw strength is so completely over the top that this is what cools the vapor down, think again. It's got asolutely nothing to do with that, as I am still only doing normal 2-3 second drags with the airflow setting half closed so only the bottom row of air holes are open. So then, what's my secret? There is no secret. It's just how airflow works if both the airflow setting and the positioning of the coils are done right and the properties of the coils are simply in line with that. These are Ni80 alien (i.e. regular 3-core alien) coils, 29g/36g at 7 wraps, 3mm ID. Nothing complicated.
But if you are used to doing 7 second draws and you refuse to do 2-3 second draws instead, then yes, naturally you are going to burn stuff up if going this route.
