RE: Kanthal question
My experience  is that two coils say 5mm long would be easy to keep juiced, but one coil 10mm long  would stand a good chance of dry burning. And as mentioned, surface area plays a good role in vapour production and to a degree flavour. One coil at .2 will have the same power as two coils at .1 at the same watts, but less surface area. 

*After reading that back it makes less sense than when I wrote it, but I'm gonna let it fly anyway Wacko2

RE: Kanthal question
Pros of Dual Coil - a dual coil configuration typically produce higher amount of vapor than a single coil build. The reason for that is the amount of contact area between e-juice and coils. Two coils immersed in e-juice transfer heat faster and to larger volume. They also tend to deliver that vapor in a shorter amount of time - they heat up the juice quicker. This means on the whole a bit better flavor. However, they consume a lot more juice and as you probably know are harder to build. How often do you have to fool around with your coils to get them both going equally? Occasionally I just rebuild a coil on my dual because one just is not cutting it. Duals also eat up you battery life faster. This is because they are lower resistance than a single almost always.

RE: Kanthal question
I think I'm going to see how things go with the single coil. I built mine to just about an ohm as mentioned, and I built the wife's to .75, just to see the difference in juice use, clouds, flavor, battery life, etc. So far I have no issue with my single coil setup so I'm going to see if I net noticeably better battery life.

RE: Kanthal question
If you put in two identical coils, you are halving the resistance. Which will double the power assuming the battery is up to the job.

RE: Kanthal question
I get the resistance thing. The main question really was, are duals just remarkably better than a single. And I asked because duals is all I've ever known outside the Nautilus. Glad to hear all responses.

RE: Kanthal question
TBH I have no idea. My preferred atomisers these days are all but one multiple coil devices. My favourite is a single coil device with which lung hitting is impossible. Everything else i actually use is designed for dual coils and gets used with two coils.

A lot depends on the power level that works for you. Past about 30-50W, more than one coil is pretty much required to stop burning the juice/wick

RE: Kanthal question
seems i still have much to learn about rda builds . admittedly i am my own worst critic , but self criticism drives me to push on. perhaps i need to hit the vape shop and get some pointers . much easier to figure some things person to person.

RE: Kanthal question
I've been building and vaping RDAs for four years and I still have much to learn. Which wicking material is best - sheets, cotton bacon. rayon/cotton mix., silica? What type of coil is best - tiger, clapton, twisted, fused? Which wicking method is best - scottish roll, coil wrap in cotton, etc.? I have my preferences but I learn new methods constantly. I will not even go into which type of atomizer is best, lol.

We learn new things are we stop growing. This hobby - vaping - is constantly evolving and how deep you want to get into it depends on your personality. Some vape just to stop smoking others vape for the enjoyment of handling new devices (of course not smoking is a big plus).

RE: Kanthal question
Yep, the cell lasted a good bit longer than the usual. Wasn't the happiest with the short fuse, so to speak. Didn't give me as long a draw because the single coil heated up quicker. So, back to the geese and giggles.

I got bold and put a tri-coil setup on it, 26ga A1 janthal, 2.5 diameter, 8 wraps, reading .356 ohms. Of course the voltage is way down and the amps are way up, so bye-bye cell longevity. But no doubt it hits better with a warm vapor. Going to compare it to the past experience with the duals, just because. It's in a pyramid shape so I'm not sure how the top will wick compared to the lower duals.

RE: Kanthal question
ok got a few pointers, 1 torch my twisted kanthal to kill the spring , 2 do an extra wrap and peel off the first . and 3 be patient , im doing fine for a newbie to dripers .
