TC vs Sub Ohm

[Pjump]

So I got an rta on my DNA40 and so far I've stayed almost exclusively to TC, mostly due to the ease of nickel coil building,

But I was wondering given I'm vaping at 430f limit is this really sub ohming? Yes the coil is .17 ohms but what's the real difference?

Should I change to sub ohm proper or is this just safer and better?

Very confused.

"Sub ohming" generally refers to using kanthal or nichrome (not Pure nickel) at resistances below an ohm. kanthal and nichrome are both much higher in resistance than nickel. In fact, people who make NR-R-NR coils use nickel as the non resistance legs. The reason nickel is used is because the resistance change as it heats up can be used to accurately measure the temperature. (TL; dr? temperature control is not subohming in the normal sense. But it still rocks.)

Technically, vaping in temp limiting mode is sub ohming (below 1 ohm, and building as high as 1 ohm is pretty much impossible with nickel wire). With the same mod you won't have much of a difference experience in temp and non-temp limiting mode, except that you'll get dry hits if you have your wattage set to high in non-temp limiting mode.

So I won't notice much difference changing from one to the other then? How about dual coil or multi coil what's the difference there?

Well, temp limiting itself does bring changes. A smother vape as the mod tries to maintain the temperature (if you've set the wattage correctly), in contrast to wattage mode where the coil will heat up as long as you press the button, and heat up even more on each consecutive drag if you chain vape. No dry hits and a cleaner taste for a longer time, in contrast to kanthal where you'll wear out the wick quicker due to overheating it. Some people taste a difference with kanthal vs nickel coils, I don't. So, there'll be differences, mostly benefiting temp limiting, but in my opinion it's nothing radical (if you've set up everything optimally).

As for dual coils, to you'll get more vapour (and theoretically more flavour due to getting more vapour), but you'll need to increase the watts some as you're now powering two coils. I've favoured dual coils, but that's because the tanks I've liked the most are designed for dual coils. Both are good, and my current new favourite is the Subtank Mini, which is a single coil. Single coils are definitely easier to build as you don't need to get two identical coils.
