Dual coils at different resistance?

[WampusTheCat]

I got this idea of having dual coils with different resistances, say a 1 Ohm coil and a 1.5 Ohm coil, as certain flavors may taste slightly different at different temperatures. You could get the initial fire of the lower res coil and then an added note when the second one heats up more. Has anyone tried this here?

On a related note, what if you had two coils of the same resistance, but one was a 28 AWG and the other was made of a different gauge or even flat wire.

Any thoughts? Should i try it out and let you know the results? Im addicted to building coils so it wouldn't really be a waste of my time. Sometimes ill build once or more per day, but usually around 2-3 builds a week. If anyone has any experience on this subject, please enlighten me

I've done it before. It's a pain in the .... The hotter coil eats juice faster.

Only thing I can say is make sure to keep the hotter coil tipped in a way that the juice flows/puddles around its wick. In my experience it's not worth it whatsoever.

Mind that the resistance does scale in some unobvious ways. If you dual coil a 1.5 and 1.0, that's not a huge deal. A wide spread in the dual coil resistance could cause some issues.

Resistance on the total coil will always be lower than the coil of least resistance in the set. Most people assume that it'll be the average...nope, combine a 1.5 ohm and 1 ohm coil, and the total resistance of your head is 0.6 ohms.

I'm not sure what would lead anyone to think that resistance would be the average of the two coils (of mixed resistances) if they already know that two 1 ohm coils is .5 ohms.

Ill probably end up giving the two ideas a try once i get my two TOBH clones from FastTech. I currently only have a Kayfun 3.1 which i don't like duals in, and my IGO-M which is a blast for every setup I've tried so far. I love trying new things on it.

There is no point to this. You want your coils and wicks as even as possible for even wicking. With uneven coils and / or wicks, you will have one wick dry as a bone, and the other still juiced.

You want your coils to heat up exactly at the same time, and glow perfectly equal. And also you want your wick perfectly even across your coils. (For optimal vaping).

But you can do anything you wish. There are no special rules of what you can or can't do.

My Aspire CE5s are like that. I forget what the two different resistances are, but they are not 3.6 and 3.6. I believe it is 5 and 3.
