What do?

So, I've been playing with rebuildables for a while now. Mind you, nothing silly, just plain jane around 2 ohm rebuildables(for the flavor not cloud chasing). I have run into a few questions that boggle my mind a bit, so I'll just let her rip....

1) Dual coils, I've mostly stayed away from them, because, as far as I understand, with a VV device they really aren't necessary in terms of flavor and production. I've yet to be disappointed with single coils, but I have some RBA's that came dual coil, and pretty much said "cool, quit eating all my juice". My question is, how does one go about building DC's while maintaining reasonable resistance? A 2 ohm DC would be two 4 ohm coils right? That seems like roughly 16 feet(hyperbole) of 32g kanthal, and I can't imagine wrapping enough inside something that doesn't have a foot between the posts.

2) What's with all this low(er) ohm vaping on mechanicals? 95% of the time, I'm vaping away on my Provari, and just tune the voltage to the resistance on my atty, which usually works out to roughly 2/1 voltage/ohms. How the heck does a 1 ohm coil taste like anything but a turd covered in burnt hair on a fully charged battery with a mech? Honestly, my 1.8 ohm coils start to taste like garbage at 4.0 volts.... Am i missing something?

Oh gosh, why are you even messing around with dual coils? I think you might be getting a bit ahead of yourself here. You have RBA's that came dual coiled? Excuse me, but did you get these off Ebay? Craigslist?

While I'm most assuredly not what's regarded on this forum as a Veteran Vaper, I've been doing mechs and RBA's long enough to know better than just dive into dual coiled stuff, and I know what works for me. On my AGA-T2 I get along just dandy with a 400 mesh wick rolled good and tight that has a 4/3 wrap 28g kanthal coil on it at .8 ohm. I get good vapes off that, plenty of cloud and good flavor.

The lower ohm stuff that you ask about ( less than 1 ohm) is where those who use mechs with RBA's on them quite naturally find themselves, having eliminated the artificial ohms barrier of regulated mods and being free to find their personal vaping sweet spot. The nice thing about this approach is that with an RBA on a mech you get a much more efficient vape. It's FAST!

You aren't holding that button down sucking on your rig for a vape for several seconds, it happens RIGHT NOW. And it happens right in your personal vaping sweet spot that you have dialed in with your build on your coil and wick, the way you have learned to make them. This is the art of vaping on a personal level.

So yes, you have been missing something.

I'm not "messing around" with dual coils, and, for that matter, dual coils have been around for quite some time in replaceable gear. Lots of RBA's come premade with DC configurations. Some of the IGO series, the Ithaka, cartos, clearos etc. It's not some mystical thing. While I appreciate the reply, I do not appreciate the condecending tone you pretty much took off the bat...

My questions were more in a theoretical sense because I've never built a DC due to the lack of ohms they tend to generate, and the lack of necessity due to VV/VW devices.

I am in no way asking or advocating sub ohm, and my questions didn't lead there as best as I know.

In terms of "it's fast", I've seen many a person take a long draw from a low ohm atty on a mech. I just don't get how, through my ignorance, a .8 ohm coil on a 4.2v power input would taste like anything but crap. I'm not saying it HAS to be terrible, I'm simply asking for the mechanics of how that works based on my personal experience.

I was under the impression this forum advocated learning before doing.... I suppose the alternative is to grab a .2 ohm, throw it on a fasttech 13 dollar mech, and see if I blow my face off?

People should REALLY try searches before posting up the same old BS again. There are probably hundreds of threads on sub-ohm vaping.

Basically, thick wire (low gauge) = low resistance = quicker heat up, BUT less actual HEAT. They run much cooler than a similar resistance with say, 32 gauge wire.

Now, go search.

So then lower gauge wire results in less maximum heat or just slower rise to maximum? I thought the relationship was directly correlated to resistance/volts. I guess the question then becomes, why vape a 28g(for example) .8 ohm coil at 4+ volts, when the heat level would be similar on a 2 ohm coil of 32g?

I don't doubt the art of finding the "sweet spot" for any particular person. I'm just trying to understand if it's mathematically similar to vape lower gauge wire that heats up more slowly as opposed to higher gauge wire that heats more rapidly.

It's actually really fascinating to think that someone was particularly less satisfied with an RBA at 2 ohms with 4 volts, even though the flavor and vapor is superior to a carto or clearo, so they decided to drop it super low on a lower gauge wire and found something they liked better. Again, I've never taken a drag on a sub ohm coil, so I don't know if it's like finding a unicorn, but it's kinda crazy to think about that level of dedication to a possible "amazing" vape opposed to a "great" vape.

Lower gauge (thicker) wire, heats up quicker, but doesn't get as hot. Search young grasshopper, search until your heart is content.

Which is why people go into the sub-ohms, to get the heat they're trading for the quicker heat up. Then when you get into cloud chasing, they want it really hot to produce tons of vapor and make the air holes bigger to cool it down before inhaling. As far as dual coil, you're right. 2 4ohm coils will give you 2 ohms. The advantage apparently (I haven't tried it yet myself) is that the greater surface area gives you more heat at the same resistance.
