I use 1.5 ohm dual coil tank cartomizers. They provide a warmer vape without burning the eliquid. I agree you should only use them with a PV that has a strong enough battery to handle them. A straight 3.7 volt PV just won't cut it.
I don't have a Kick but do use a Darwin which the kick is based off of. I have absolutely no problem using regular dual coil cartomizers or tank dual coil cartomizers with the Darwin. At 12.2 watts using the 1.5 ohm dual coils, they adjust to 4.4 volts and provide nice warm consistent vapor. And even being a heavy vaper, I still get 18+ hours on a charge.
Ok, first off I've never heard of a dual coil atomizer. Most atomizers don't use a coiled wire but instead, they use a steel mesh.
You may be thinking of dual coil cartomizers that are pre-punched and put into a tank.
A single coil cartomizer is just that...one coil. It will be rated with an ohm ratings like 1.7 or 2.0 or 2.5, etc.
Dual coil cartomizers have two coils running in tandem. These are usually but not always rated at 1.5 ohms. So you have in theory at least, two low resistence coils which produce greater amounts of vapor and obviously go through more juice.
If you plan to run dual coils, I would only advise you to do so if you already have a variable volt device or a higher volt fixed device. Standard 3.7 volt vape set ups just aren't powerful enough to run a dual coil to its real potential, because those two 1.5 coils really just equal a 3.0ohm resistance. Something like an ego battery (non twis) can't keep up. You need to hit a dual coil with higher voltage.
Also, if you are using a kick in a tube mod you will be disappointed with dual coils. This is because the kick will read the dual coils as a single 1.5ohm and adjust you voltage accordingly to get the desired wattage.
A kick is a small electronic chip type device that turns any tube mod into a variable wattage device. This is different from a variable voltage device.
What you do with a kick is, figure out what your wattage sweet spot is. Say it's 7.5 watts for example. You adjust the kick to 7.5 watts and insert it into the mod, screw it all back together. Now regardless of what type of atomizer, carto etc that you put on there you are going to get 7.5 watts. If you put a 3 ohm on there, the kick will sense that and adjust voltage to give you 7.5 watts. If you put a 2.0 ohm there, same thing, it adjusts voltage to give you 7.5 watts. This is true.
The problem comes in when you have dual coils because the kick is fooled. Instead of reading a dual coil at the combined resistance of 3.0 ohms, its reading the whole thing at 1.5ohm and is making its voltage adjustments based on that instead of the true 3.0 ohm resistance. This is false. The kick is reading 1.5 ohm because that is the effective resistance of the circuit. A parallel circuit. A 1.5 ohm dual coil cartomizer is actually 2- 3 ohm coils in parallel. You need to look at parallel circuits to understand how a dual coil cartomizer works.
If you tell me your set up, I can give you some options that would probably work for you.
Seeing you two guys from LA makes me sad I missed Mardi Gras.

If you're referring to using cartomizers in a tank, both single and dual coils work for me. The advantage of dual coils in general is that it's harder to get a burning vape, as those two 3 ohm coils in a typical 1.5 ohm model won't scorch the juice easily. They work fine in tanks and also by themselves. I find single low resistance coil cartos - 1.7 - 2.2 ohms - require frequent "topping off" when used alone or they can easily burn and leave you with a bad flavor. As a result I only use LR single coils in a tank so that they stay wet at all times.
I've used 1.5 ohm dual coils on regular 3.7 volt mods, from the ego on up, for over a year and they haven't given me any problems whatsoever. I'll still use them alone or in tanks, while single coil LR cartos only go in tanks for me. Good luck finding a good fit for you!
I've actually had just the opposite experiance. I prefer the single coils over dual coils as I don't get the occassional burnt taste I got with dual coils.
My personal theory is as a carto in a tank is vaped, the upper to mid-portion of the cartomizer can become dry just from the suction action of vaping. You can see this after vaping for a while, the top of the polyfill appears dry no matter how well you prepped the carto prior to inserting it into the tank.
With a dual coil carto, the upper coil lies somewhere in the middle of the carto. As juice is sucked down, that carto may not get enough juice to keep it from burning the polyfill that surrounds it.
A single coil's heating element is located toward the bottom of the cartomizer, where it is kept bathed in juice continuously, so no burning of the polyfill. The below cut-away diagram of a cartomizer shows this (click to enlarge detail).
