I'm fairly new to rebuildables, and I love what I'm getting out of them so far. I haven't ventured into sub ohm setups, I'm quite happy with a 1.2 ohm single or dual coil setup. I don't understand the appeal of an unstable sub ohm set up that could potentially hurt oneself when you can operate at a safer resistance and simply up the voltage/ wattage.... Is there a significant enough difference in performance to risk injury if something were to go wrong? Why use a mechanical and run it at .2 ohms (or whatever) when you can use a 1.5 ohm coil on a provari or a dna20 or a vamo (or whatever) increase the output of the device, AND have the protection of the device? I've seen videos by riptrippers where he's getting vapor production equal to that of a mechanical sub ohm setup but he's at 15-18 watts on a coil that's not sub ohm, and it's much safer. Am I missing something here?
Also, it seems to me (based ignorantly and entirely on common sense) that in such a scenario of catastrophic failure resulting in a battery actually causing bodily harm, wouldn't it heat up sufficiently enough to warn the user? I feel like you would drop a superheated mod rather than grasp it, continue to vape, and blow your face off... Or is there something else that I should know?
