I am also expecting such reply.. Lol
First, it doesn't necessarily to be virtually melt for it to combust and reacts with the chemicals in the atmosphere.. Say, the coils suddenly have hard hotspot till it snaps, can you figure how much is the temperature at the point of hotspot before it snaps? At that moment, some chemical reaction could be happening.. I say, could..
Aluminium, yes most if not all metal compounds hazardous to health, but the aluminium u said could bind to brain or nerve cells upon direct exposure to the atomic compaund, which in this case is somwhat irrelevant as compared to the potentially carbon monoxide production from nickel due to catalyzed by combustion. Also, aluminium may contain nickel (depends on type) but at negligible percentage as far as carbon monoxide is concern.
And going along with your logic as well, if you know your juice contains diacetyl, acrolein and formaldehyde, wouldn't you want to steer to other type of juice that does not or contain minimal amount of that substances? I would. If you wouldn't, then your logic is self explanatory.

Am i a gibbering paranoid mess yet? No, its called "precautions" not paranoid.
My point is simple: i will minimize the hazard risk anyway i could. Its personal choice, anyway

I say, could..
but do you have any proof of it? I think not. Wires don't snap by hotspots alone, inherent, or introduced weaknesses also contribute to it. When a wire snaps, what happens? No more vapor...so what's the problem?
By your logic,
No wire is safe to use. I purposely brought up aluminium (in kanthal, which you did not choose mention in conjunction with it), and do you even know what temperature and heating period/conditions is needed in order for nickel to act as a catalyst and create CO? I think not.
And it's obvious you don't know how acrolein and formaldehyde come about, if you think it comes in a bottle of e juice

As for diacetyl, do u have proof that vaping causes intake in amounts large enough to cause any harm? I think not.
The very fact that you have to ask about nichrome and TC shows that you really need to know more. It is because of people like you who prefer to listen to scaremongering and sensationalist reporting, and erring too far on the side of caution/paranoia that will cause vaping to fail, and give more ammo to those who have vested interests to see it fail or be banned.
You can indeed claim "personal choice"/play safe and that is your right if you can't be bothered to find out the truth, the proper facts, and actual situation. But usage of such paranoia/ignorance to perpetuate scaremongering is irresponsible.
