Sure about that? Remember, we're talking wick volume now, not wire volume. I thought a fat wick was generally better than a slim one?

It gives you a more efficient coil for the same size of wick.
You're probably right as a rule of thumb, but it isn't simple; otherwise nobody would use nano coils.

The number of wraps you get on a coil is dependent on both the resistance you want and the gauge wire you're using. I use 27 gauge. Coils made with thicker wire have a lot more surface area compared coils made with thinner wire both of the same resistance or of appropriately less.
The vape is also dependent on air flow and wicking, so comparing just single vs dual coil setup is almost meaningless.
I run dual coils in a Trident dripper at 0.5 ohms, single coil IGO-L at around 0.6 ohms and a AGA-T Geny with SS at around 0.6 ohms. All these have air holes drilled to what I like and the Trident is adjustable. How many minutes of vape time you get per charge on a mech depends on the final resistance only so all these are about the same.
I vape zero nic, so there is no TH. The Trident is the vapor and flavor production winner. The IGO is third in vapor production and a tight third in flavor. The Geny is second in vapor production and flavor but also has the cleanest flavor out of this bunch. I think I did not spend enough time with the IGO and with a bit more work, I could make it better. I don't use it much anymore.
I have tried the Trident with a single coil once when I broke a coil. I went to a single air hole and tried different sizes. Of course the single coils resistance was half the dual, so power was much less. It put out a surprisingly good vape, but no way near what the dual coils do. I should try it with more power some time and see how that goes, but it's so good with two coils I have very little incenntive to do it
They all vape different, the same juice tastes different on each and I really enjoy the Trident and AGA-T.

I vape a Trident V2 mostly but have other attys. I use 28ga 12 wraps each coil @ around 1.0 ohm. This Trident hits like a beast and is my all day vape. I change the battery out when the voltage drops to low vapor production and that's not but once a day.
If you have 2 coils rather than 1 and the overall ohm is the same and you run the same voltage youre not getting the dual coils hot enough to make it a better vape. You need to increase your voltage/wattage on a dual coil build. If you like a single coil at 1.3 ohm what you should have is a dual coil setup around .7 ohm at the same voltage to get the coils equally hot to your single coil setup and experience the better vape
I built one of these in my Octopus dripper with two cotton wicks (Google bunny rabbit build or something like that). I used 30g Kanthal and it came in at 2.7 ohms but hits nice at 5.6 volts on the Provari.
Built properly at the proper wattage as compared to an equivalent single coil, dual coils will provide more vapor and flavor.

One should consider the simple things first; if your using more juice and not getting more flavor and/or vapor, you are doing something wrong with your setup.
If you are effectively vaporizing juice on one, two, three, four, or any number of coils it is because you are building to the juice flow limit of your device.
Your goal is to vaporize juice as fast as it can wick, nothing else.
The temperature of a vape has more to do with volume of vapor retaining heat than actual coil temperature as it is vaporizing juice. A larger mass takes longer to cool. All vapor starts out at pretty much the same temperature, it just kinda happens that way.
So if you run multiple coils, each using the same length of wire and each coil has its own wick (also sized identically) verses a single coil sized just like one of the coils and wicks in your multi coil rig, all wicks feeding at a similar rate, all coils reaching the proper temperature regardless of ohms or battery life, the multi coil setup will produce more vapor, deliver more flavoring, and the vapor will retain the original vaporization temperature longer (assuming similar vapor chamber size).
Burning juice happens at the coil, when the juice flow is slower than the vaporization rate. Otherwise the vaporization temperature is relatively the same between one coil and a multi coil rig.
If your equipment is able to flow enough juice to out supply any single coil build you can fit in the device run multiple coils, with the appropriate battery and all other safe use methods.

I'd just like to say congratulations everyone!
I haven't seen a single person write "duel coil", and that makes me very happy

I went to dual coils but the additional battery drain and the increase in juice usage just didn't seem to be worth the difference in vape quality.
It reminds me of Gillette continuing to add additional blades to a razor
Exactly ...
I also tried replacing my 28 AWG single coil with another single coil made from 2 pieces of 32 AWG twisted together. I made sure this new and improved "twisted" coil was the same ohms as the coil made with the single strand of 28 AWG.
Result .... No difference .... big waste of time!
So you are vaping at 27 watts. I would expect there to be plenty of vapour. On the other hand, I would also expect there to be the same amount of vapour from a single 2 ohm coil running at 27 watts.
However, to manage to do that would require stacked batteries or a high power regulated mod, and not many people have that sort of equipment.
my friend, you are doing it wrong. 2.6 ohm coil won't give you much vapor and two of those wont give you much more vapor because you don't get twice the vapor in dual coils you get at most 75% more vapor.
I suggest you test you build a .5 dual coil (1 ohm each) and test it against your other device at at .5 ohm
you will be pleasantly surprised. When happens with low sub ohm is that the increase in vapor suffer from diminishing return. So there's a break point where dual coils will outperform single big a huge margin
you are basically trying to disprove lots of vapers who swear by dual coils. stop and think for a moment, are you sure that you are more knowledgeable than them?
You obviously don't know what you are doing just yet, you'll get there.
example: I have yet to see someone claim that kayfun output more vapor than aqua.

I hope this coil duel will make you even happier.
Its good to know you found a happy place for your device; still ohms don't do the burning that's temperature accumulation in a coil with little or no juice flow.
Its very much like boiling water in a pan, if you put a pan on a high flame the pan will eventually glow red hot. But if you continually fill the pan with water at the same rate it boils off the pan will never get overly hot.
It would be fantastic if our devices were regulated by coil temperature real time, that would eliminate burning. For now we run on indirect regulation, sort of like expecting one throttle position to maintain your cars exact speed regardless of the cars load, or if it is climbing a hill or descending the other side.
If your cars throttle is fixed, and you want a stable speed you need to adjust the road, in our case it isn't the road but juice delivery. More or less flow to the coil is what works to ensure the coil remains in the optimal temperature range.
I think the advantage of multiple coils is that they tend to be shorter, thus juice doesn't become depleted prior to reaching a still heated portion of the coil, this is especially the case where each coil is fed by its own wick, and even more so if the wick feeds both ends of the coil.
Run correctly multiple coils just produce more vapor, sure it will deplete battery charge faster, but if your wanting lots more vapor, it is going to use both more juice and more power from your battery. Given similar coil and wick design.
Different wicks and coil designs aren't exactly side to side comparisons. Certainly when all that counts is if the coil vaporizes your juice.

While it would likely only fit well in a huge box mod with an integrated atty, and be hugely expensive, and technically difficult... this could work! I'm thinking infrared thermometer hooked into a fancy VW module that could regulate voltage accordingly, keeping your coil at the "perfect temperature".
Where are our electrical engineers?
Wellsaid Maurice, and each of us has our happy place with coil builds. For me sub ohm if too low an ohm like 0.5ohms for both coils is way to hot. My happy place is dual coils at close to 1.0 ohms. Plenty of vapor and doesn't get near as hot. I was vaping at 0.5 ohms and burning my tongue, along with wasting juice imo, and shortening my batteries life.
2 x 12 wraps @ around 0.9 to 1.0 ohms, perfect!
Why complicate it? Everything you need to know is right here:
When we’re talking about ohms and ecigarette parts what we’re really concerned with is what kind of heat the coil is generating to evaporate our eliquid.
There are effectively 2 things that determine how hot the coil element gets; battery voltage and the ohm rating of parts attached to the battery. Higher battery voltage and lower resistance both create more heat for evaporation. Heat produced by the ecigarette will impact flavor, vapor production and your overall experience. Using ohms we can fine tune the vapor production and flavor that best matches the batteries we own.
