What??? Has Vurve lost his mind? Two in one day?
That's right.
Just another legacy article for you guys.
However, this article truly showcases what I have been envisioning with most of my old articles, so hopefully you start to understand why I took the originals down. It's a lot more content. More in depth analysis. All around a better article.

#Getting Setup
#Atomizer
As most of you know, your number of choices here are nearly infinite, so how do you know which is the best one for this?
Well, for starters, an RDA is going to be your number one choice here. They are quicker to rebuild on, have better flavor, and you are not committed to a certain flavor for the period of time it takes you to finish a tank.
Even as RDA's go, you have several different options:
-
Side Airflow - This seems to give the most well rounded flavor profile. In addition, side airflow is generally more adjustable with the ability to close off a side if necessary, because you are going to want to be doing most of your testing on a single coil. If your RDA of choice is already a single coil setup, even better.
-
Top Airflow – In my experience, top airflow devices do give great flavor, but they often lack adjustability. Since we likely won't be running a full standard setup, you may not have an RDA suitable for the level of ease of use we are striving for.
-
Bottom Airflow – In my personal experiences, bottom airflow tends to be very airy, leaks a lot, and just not very strong on flavor. If you have one that you really enjoy and think would work well for flavor testing, then go right ahead. Flavor is subjective and it will give you a better feeling of how certain flavors will taste in your favorite device.
My Personal Choice: Side Airflow - Vaporesso Transformer and Royal Hunter. They are both very smooth, have adjustable side airflow, great flavor, easy to build on, and can run in single or dual coil.
#Wire
Admittedly, I haven't not tried every single wire on the market, but I can give some insight on to what I have tried.
-
Kanthal A1 – Generally regarded the the go-to wire. It's safe at higher temperatures (as far as science has lead us to believe so far), easy to use, and has a great resistance - allowing you to do a lot of different types of builds within a reasonable amount of space. However, I find the flavor to be a bit metallic. I love this for long term builds in my atomizers, but it leaves something to be desired when you want to taste the juice, and nothing but the juice.
-
Stainless Steel (316L) – Also generally considered a safe wire, if you know how to use it properly. Be sure to head over to /r/ECR and do some research if this is the route you decide to take. By far, the cleanest tasting wire I've used to date. No metallic aftertaste. One downside is that is has such a low resistance, it can be difficult to fit your build into your device if you are not trying to go below 0.4 ohms. However, since we are aiming to run a single coil build, this shouldn't be a problem for our single flavor testing.
I have used many other wires than these two, but they don't seem worth mentioning because they are so subpar. Titanium and Nickel require being ran in temperatue control mode, which makes single flavor testing more difficult than it has to be. In addition, while ceramic coils produce amazing flavor, these are known to dangerous to use for their potential negative health consequences and shouldn't be considered at all.
My Personal Choice: Stainless Steel (316L) all the way. Super clean taste. Easy to build with. Can be built into claptons. This wire has quickly won my heart and is slowly being integrated into all of my atomizers.
#Wicking Material
Same with the wire, there are a lot of different wicking materials out there, this is just an assessment of the ones I have tried.
-
Organic Japanese Cotton – Very neutral taste, soaks up a lot of juice, and very inexpensive. As long as I gently wash my hands before handling the material, there is very little to no break in time.
-
Bleached Cotton Squares – This is the cotton you can find in most B&M's retailing for $4 for (5 PC) 1.5” X 1.5” squares that is white as a piece of paper. The fibers in the cotton are usually non linear or do not reach throughout the entire length of the pad, generating bad juice flow. Has an off-flavor and generally requires a moderate break in time. Grossly expensive in stores, but can be bought from any online vape supply shop for a fair price.
-
Cotton Bacon – About the same color as the bleached cotton squares, but has little to no off-flavor. Soaks up juice about as well as the organic japanese cotton. The fibers in the material are non-uniform. Requires little to no break in time. Very expensive.
-
Native Wicking – Some sort of hybrid cotton/rayon blend. Perfectly linear fibers and wicks exceptionally fast. A slight off-flavor requiring a little break in time. Very expensive.
-
Rayon – Very linear fibers. Rather than expanding when it soaks up juice, like cotton does, it contracts. This minimizes the amount of juice it can hold, which is vital for our flavor testing. Moderate to long break in time, but you must wash your hands before handling. It picks up all the oils and debris from your hands. Fairly inexpensive.
My Personal Choice: All the benefits of the organic japanese cotton make this one a no-brainer. I still have lifetime supply of this stuff, which works out wonderfully since it works so great. There's nothing wrong with the Cotton Bacon, aside from the cost. It works very well too.
#Wicking Method
Wickless
Clapton wire is an absolute necessity if you are going to run this option due to its ability to act as a wick and hold juice. Ideal diameter is about 1.5-2mm at 5-6 wraps, no spacing. This setup allows the coil to hold as much juice as possible due to surface tension. With no extra juice or wick to cool the wire off, you want to be around 15-20w. You will get exactly one hit from this setup.
-
Pros - Very fast tasting method. No need to stop and rewick. Especially helpful if you have a big back log of flavors that need tested.
-
Cons - Hard to get a good grasp on less potent flavors from the mere whisp of vapor. You'll probably be vaping wire and tasting metal at some point.
Half Wick
Single coil setup, empty slot closed, Clapton wire at 2.5-3mm diameter. Wicking is pre-measured and rolled to fit exactly the length of the wire. No tails on wicks. I'll have about 20 or so wicks prepared before I start testing so I save time. This is my favorite setup. Good for when you get a new order and need to taste 5-20 flavors in succession.
-
Pros - Allows for a more full flavor than wickless. You get about 2-3 full hits. Quicker to setup than a full wick.
-
Cons - A little slower than wickless, still does not provide a 100% full vape flavor. You could run it dual claptons with half wicks to increase overall flavor, but then you are making the process even slower.
Full Wick
As the title says, it's a full wick. Use your preferred wire setup, single or double coil. Claptons are still encouraged, but not necessary. Your wick will be providing juice from the well and you don't have to count on the wire to hold all of it.
-
Pros - Allows for a full, true flavor. Good for analyzing a certain flavor over a longer period of time, perhaps for something more complex.
-
Cons - Takes a good deal of time to repeat this rewicking process for each flavor. If you don't rewick, the flavor will be contaminated with the previous flavoring.
My Personal Choice: When I have a huge backlog of flavors, I will always go with the half wick method. In my personal opinion, it's infinitely better than the no wick, which is almost pointless to attempt. Even if it takes a little more time, I at least get to truly taste the flavor. If I'm working with a certain range of flavors where I want to deeply analyze each one, I will mix up a 10ml batch of each flavor, and do a full wick method so I can steep it and continue testing throughout the day so I can think on it a bit better.
#Conclusion
There are several options for doing your single flavor testing. There is no right answer and it majorly depends on what you are trying to achieve. Most importantly though, just get your single flavor testing done! Once you know your flavors, you can begin to understand how to utilize them in a recipe.
> My Personal Choice: Stainless Steel (316L) all the way. Super clean taste. Easy to build with. Can be built into claptons. This wire has quickly won my heart and is slowing being intergrated into all of my atomizers.
I've always said this, but my friends didn't listen and they are still using the crabby KA1.
For me, when I went SS316L I never went back again.
He says to be safe with it. I thought it was safe to dry burn and use in power mode?
Yes it is safe to dry burn and use in power mode. In fact, I use it exclusively in power mode only. Keep in mind that when you are dry burning SS, don't put too much power on it and don't glow it much. I read somewhere here that you should use maximum 30 Watts for dry burning. Dark orange glow is what you are looking for. Just find the hot spots and remove them and you are ready to keep vaping for good!

Glad these are making over to DoD. I was looking for the flavor review one at work yesterday but I guess it's not up yet and I didn't have the google docs link handy.
This will be really useful.
Have you gone into detail on mixing for flavor tests before? I think that would be somewhat helpful. Like, mix 5-10ml @ .5, 1, 2,5,10% flavoring? I don't know. Usually when i'm testing something i'll mix at .5, 1 and 2-5 and let it steep a bit but maybe there's a better method.
Wondering what your thoughts are on nichrome 80 wire? If anyone else would like to share their opinion i'd be glad to hear it!
I've heard the flavor is as good as stainless, but I've never tried it myself. Thus, I have no input.
Thank you for commenting what you've heard :) I like it better than Kanthal A1 because has a bit lower resistance which leads to bigger clouds and faster heat up time (At least I think that's the reason). And when you heat it up for the first time it turns blueish green!
Between these Modest Monday posts and your podcasts, you have definitely helped me get started right and with a level of confidence I didn't have when I first attempted mixing 3 years ago. Back then it was a miserable experience and I dropped it. With your help I feel like I (kinda) know what I'm doing now. Keep up the solid work. It's greatly appreciated.
There is nothing in this article I can disagree with. My way is almost exactly has yours, bud. I use my Royal Hunter and my Transformer (Thanks for the recommendation on that, btw). I also have a few Derringer clones too, that I can squeeze a single fused clapton in (2 26g/36). I really am liking SS, as of late. But still tend to lean to a Kanthal core and ni80 wrap. SS has a lower resistance and doesn't last as long as my usual fused claptons. But this is due to a little bit of laziness on my end. I have had these discussions about single versus dual coils before. But I stick to my word that, when single flavor testing, I feel using single fused claptons give me the best impression of what to expect of that concentrate.
As always, great write up and thanks for sharing!

There's one of the two I've been waiting for! And pretty pictures version of the half-wick method is so much better than the potato-quality one I recall from your previous single-flavor testing post. Please get the text up soon.
Should be about 30-60 minutes. Waiting on fiancee to get off work, so I'm sitting here in my car with nothing to do.
She's probably going to want food afterwards though...
Feed your lady. I was just being lazy and not wanting to move my mouse the few inches necessary to remove "User Reports: Spam." Which is not entirely undeserved without the full text, but kind of jackass thing to do in light of "Don't shit your pants just yet."
This right here is amazing. Thank you very much. I will implement the half wick method.
When you said to be safe with the SS 316 what do you mean? It can be dry burned just like kanthal right?
Ok. So here's the process.
- Wrap your coil and install like normal. Best to leave spacing to avoid hot spots. Use a coil building app or resistance tester. It's a very low resistance wire.
- If your mod has pre-heat, turn it off. Turn mod to 10-20w. I usually do 15w.
- Pulse wire until it starts to slowly changing colors. Once you can see a faint glow of red. Immediately stop. Be sure to keep a very careful eye on the coils. Looks for hotspots. It will be hard to tell, but the stainless will color in a non-uniform fashion if there is a hotspot.
- Once you've hit this point and there are no hot spots, you're good to go. You are basically annealing the steel before you use it.
When you dry burn your coils, do it in the exact same way you prepped the coils. Very low and very slow. I use a cheap tooth brush to help get some of the gunk off rather than relying on the heat to burn it all off.
Just some background information, stainless steel has chromium in it. At a high enough temperature, chromium can oxidize to hexavalant chromium. This shit is fucking dangerous.
If you are using stainless and ever accidentally fire the coil to the point of glowing red, throw it away. Immediately.
