Really, really. What you got there is kanthal (indicated by A1) coils consisting of 4 individual 30ga wires; 2 twisted together then twisted with 2 more twisted together. It just provides more nooks and crannies for the juice to sit and vaporize (more flavor in theory)than single wire. 0.5 ohm in single coil, or double them up for 0.25 if your batts are good enough for that. The more wire mass there is, the more energy needs to be pulled from the battery. Better or worse is subjective though.
They appear to be 4 wire twisted coils using a somewhat non standard twist pattern which I personally doubt does much different than any other twisted wire. If you want to try a single wire coil that is very doable. In my experience they tend to work better. What resistance are you aiming for?
You bet and No. Temp control doesn't work with kanthal. I like stainless steel, (better than nickel and titanium) for temp control but check with your mod for compatible wire types.
Twisted coils are spit city in my experience.
You might have a point here...since it’s all I know, I’m kind of used to it by now, but I definitely have to try out a regular coil now. Squeezing the wick in should also be easier (I hate that part).
Interesting. I did some 8x28s and they don’t spit much at all. Maybeitmattershow many wires you use?
Yeah no TC on those but have fun with them. I hate threading the wick through the wire myself, I've just learned to wet it, twist it to a tiny point, and then snip it. Once I get the wick through the needle/coil, I can just worry about untwisting, thickness and etc.
hope you enjoy the coils.

My theory on that is the nooks and crannies allows the water vapor condensation to accumulate in the coil. When the go button is hit and temps rise above 212F, the water boils and "spits" the juice, which has a different boiling temp. If you dont boil the water off, it continues to spit. This is one reason I purge my atty before inhaling.
Just a theory, nothing to back it up but my experiences with twisted coils.
Haha they are a pain to thread the wick through, aren’t they? The problem is, there’s no smooth threading through it, due to the twisting of the wires...
All coils have the ability to be spitty, the coil being twisted just exacerbates the situation. What you are saying about the boiling point differential the components in the eliquid is interesting. Is there any water in eliquid though? I didn't think there was. There is a boiling point difference between VG and PG though of about 100 c.
I'm more inclined to believe spitting is just a symptom of excess juice on the coil.
Why does my atomizer crackle&pop and spit hot juice on my tongue? | E-Cigarette Forum
Another way to think of it I suppose is excess heat IN the coil. In a correctly setup tc for example there shouldn’t be much in the way of popping and spitting
No, at least not when we mix it, unless distilled water is used for added throat hit in lieu of PG. But when heat is created in the atty and then cools down, moisture is created. I think water vapor is even pulled from the atmosphere due to the fact that both PG and VG are hygroscopic. This may even be more apparent in humid climates. I think its this small bit of water moisture that settles on the coils and creates a slury with the juice that causes the problem.
Again, its just a theory. I have read through that blog about popping and cracking before, (which is very informative, thanks for that) and I've tried scoping the interwebs for supporting info on the water bit of it, but really, its just a culmination of several bits of info smishsmashed together to come up with this idea. It may be wrong, but I don't have to deal with much popping at all by simply purging my atty (if all else mentioned in your blog is addressed).
It took me a few weeks, but now I finally had time to get me a spool of wire to build regular single wire coils (I already forgot what I bought, it says KA1 on the spool, is that Kanthal? It's 24 gauge thickness).
Anyway, what a change! My biggest grief before was (too) hot vapour, none of that anymore, it's so much easier to vape now. Before, I had to be extremely careful and release the button after 2-3 seconds or the vapour would get too hot to be drawn in, even though I only vape at around 35 Watts. Less power didn't make things better, just less tasty. Now I can happily draw in vapour as long as I wish. Maybe these double-winded coils only work well with certain atomisers? I had this hot-vapour problem with both of my atomisers, a Berserker Mini RTA and Geekvape Ammit RDA (both on iStick Pico 75W).
EDIT: Maybe the single-wire coils do taste a little less intense though..
For some exotic type wires, it requires more airflow to keep them cool than with more simple type wires. If you don't have enough airflow to keep the coil cooled, your vapor can get uncomfortably hot (for some people).
That makes sense, especially for my RTA, which has quite a small air inlet hole. I wonder which type of atomiser has better airflow than my RDA (the Geekvape Ammit); if this one couldn't keep the coil cool, it really needs a lot of air (or I'm especially sensitive to heat, which is possible, but I wouldn't know).
I have not used that exact type of coil, but I would say it is more designed for wide open, DL style vaping.
Glad its working for you! Most all RDA's now will give you exactly what you want, its up to you to perfect the build most suited to that RDA. For example, both the Berzerker and Ammit are MTL RDA's. Those are designed to run very efficiently. Not much power is needed to make them shine, which also means not much wire mass is needed either. If you have it, try 26 or even 28 ga wire in there and also if you have it, SS wire feels more cool than kanthal. The big power big coils and big wire is for atties that have big air options like with the Goon. If the vapor is too hot, increase the air or decrease the power or change the wire to suite the needs. About the only constant I have found is the coils should be as close to the air supply as possible without touching in order to get the best flavor. The further the coil is from the air holes, the more throat hit. Its all a balancing act, and I think thats the fun part. If you like Geekvape, try the Digiflavor Themis RTA for more air flow. If you like vandy vape, try the Kylin Mini RTA for more air flow. Those are rebuildable tank atomizers, I may have misunderstood if you were using RTA's or RDA's as both of those listed come as both RTA and RDA. But with RTA's, you just have to pay more attention to the wicking method. Placing the coils as close to the air is still a constant.
