Hi Tyger,
Welcome to the porch! Pull up a rocker and sit a spell.
I did want to let you know that politics and other topics that aren't directly related to vaping are generally better posted to the
Older Folks and Vaping Back Porch thread. It's under the Community/Lounge topic. We generally try to keep the vaping-related posts here on the front porch, and everything else on the back porch (we don't always do a very good job of it, we do tend to wander, but that's the idea).
I don't think you'll find many cloud chasers on this thread, but there are some of us who sub-ohm. There's a big difference between a 0.5 Ohm build (8.4A max) on a 20A battery and a 0.2 Ohm build (21A max) on the same battery. The first one is almost certainly safe, while the second one is pushing the limits and is likely to result in long-term damage to the battery at a minimum, and catastrophic failure of the battery as a worst-case. So, personally, I prefer to think of it in terms of safe vs. unsafe, rather than in terms of sub-ohm vs. 1+ ohm. The important part is to know Ohm's law, and to know the safe continuous discharge rate of the batteries you're using. So, I have to add this picture:
