26g Coil Builds?

I'm about to venture into doing my own builds and I had a silly question. I have watched dozens of videos on how to do builds and have even done a couple builds on some of my friends attys. I have one friend who on all his dual builds he uses two coils with different wraps. For example one coil with 7 wraps and one with 5. Does anyone else build this way? I have never asked him why he does this and in all the videos I've watched I've never seen anyone else do it. Is there a specific reason? Just curious  

Hey guys just recently got a Lemo2, wasn't happy with the coil that it came built with for some reason so built my first one to put in. I think it came out pretty good, I believe it came with 24g Kanthal and I did 11 wraps around 3.5mm came out to 0.9ohm. It takes a while to ramp up but seems to give a nicer vape to me than the stock one which was like 5 wraps around 2mm at 0.5 ohm.

Anyways, I tossed the original coil and now am wondering if I really had to or could have saved it. When you guys try new coil builds do you save your older builds? And being that it's really just resistance wire does a coil ever really need to be replaced or is it just for novelty/trying new builds?  

I used to build new coils every night on RDA. Sub ohm tanks with coil heads became a thing and I transitioned to sub ohm tanks with replaceable coil heads. I put an old school 5 wrap kanthal build on my origen 1 the other day. I’m just wondering if anyone out there is still building RDA’s or is that a thing of the past?  

Just finished up my first build using 24 Guage kanthal with 9 wraps. It's a dual coil build that came out to .49 ohms. It's not the best looking build but for my first attempt I guess it's not too shabby. It was built on my mutation x v4. 40-45w was about as high as I could go before it got too hot for my liking. just wanted to share it.  

Hey guys. I have been in the vaping scene for a little while now. Just curious to what everyone likes to sub-ohm with.

My favorites so far.

Mutation X V3- 24 gauge dual parallel 5/6 wrap
Mutation X V4- 20 gauge dual 5/6 wrap or dual 6/7 wrap
Turbo RDA- both of the above builds work well

I've had the dark horse, doge and doge v2, freakshow, and a few other RDA's and the 3 above have been my favorite....v3 was my favorite for a while until I tried the v4, its now my favorite, and its a tie between the v3 and turbo for 2nd and 3rd place.  

well I finally got it in the mail today. And have really enjoyed vaping on it. Right now I just got the atlantis V2 on powerful plus mode. My atlantis nickel coils should be in Thursday so I can try out temp control in a couple of my tanks. I've also decided to try my hand at building even though I swore I never would. Got the mutation X V4 on the way as well. Hopefully this is a decent deck to build on. I am not a beginner really, I have wrapped a couple coils for my buddies and did a few builds on their attys. This vaping thing can get expensive! Vape they said, it'll be cheaper than smoking they said....pffft. lol
 

Well , I aint even gonna say much this thing is better than any mech mod out there . You guys told me to start building higher ohm coils and i did , I build a 2.3 ohm coil . My 2*18650 box mod performed like .... with it , I had to hold the button for 2 - 4 secconds before draw and i still got minimal vapor . So i got the istick 50w , i set it to just half of its full potention , 25W and it is firing up the 2.3 ohm coil as soon as I press the button and I am getting extreme vapor production . Also size i knew it will be small , but i can not believe how small it actually is , absolutely amazing , build quality is also amazing . I should have moved from mech mods to VW a long time ago .  

Ok I'm hoping I don't get heat for these questions/statements but educating ones self especially with something that is still very new is important to me.

1. Read some articles on how there is second hand vape similar to cigarettes (99% better mind you) what are your thoughts? Vaping may not be as safe as smokers think, research suggests | Society | The Guardian

2. Formaldehyde found in builds running at high watts/voltage? But 0% at low/normal builds, what i can't seem to find is whats considered to high for a Mechanical Mod or even for a V/W, V/V Setup? My normal build for a mech mod is twisted single coil 24 gauge 6-7 wraps, usually gets about 0.28 ohms and single coil 8 wraps of 24 gauge puts out 0.73 ohms on my flavor builds.

As you might know, the mutation RDA has a post on the outside, one large one in the middle with 2 holes, and then another outside post I see a lot of people while building on a mutation putting the leads of their coils in the outside and then the hole further away, as seen in my crudely drawn photo=p i was just wonderingwhy not feed through the closer one, it seems a lot easier? i've been just rolling with the crowd and building using the 2 further ones.  

So I was just wondering what resistances (and I suppose coils) people use for their cloud chasing builds.
Is the lower resistance or surface area of the coils more important?

My current go-to setup is a dual micro coil at around 0.18 - 0.20 ohms with 24 guage (I think 4 wraps).
