Well I hope I don't ever feel the need to do this... I can't imagine driving around in my car all day and taking a dripper out when I leave the house etc

Me either, that's why I've sold off almost everything else and have 4 REOs now, all the benefits of dripping without the downside.

I'm just trying to approximate the cloud of the ultra light cigarettes I used to smoke. As long as I can white out my face in the mirror at 4.2v there's nothing more to chase. Flavor is there with the right tank and atty. My bottom limit is about 1.4 ohms. I'm mostly around 2 ohms on a Provari or a Zmax.

I also like the flexibility of variable voltage vaping. There's a lot of difference in a mech between fully charged and ready to charge again. VV gives you some leverage.

That's not to say anything against sub ohming. It's just not my style to stand out in public behind a cloud of 30 watt vapor.

I like how this thread is absent the accusations of insanity worse; death by batt mod... lol not to mention "its a phase, and it gives vaping a bad name".

Not that safety is not an issue of course it is, but we couldn't post a thread about sub ohms (anything under 1 ohms) without stirring a whole mess of whoop asss. But like i thought, SO vaping is here to stay.

Funny this thread is put in the RBA sub forum, seems to me its more about the APV... but then again, you can't have SO without an atomizer.

What I'll repeat for the OP, regulated PVs are coming back around... for sub ohms vaping, and its not the DNA30 but we need at least 40 or 50+ w devices (and big batt capacity ).

Hmm that reminds me I have to get a better switch spring for my 26650 tube, for sub ohms.

And oh yeah, for me its the fast response time, great flavor (given good wicking, and efficient air) and yes, lots of clouds
After selling at least a doz. "good" mechs, I still have a doz. 18650 mech tubes, but I've got 2 100w double 18650 Raptor boxes, and a 26650 tube mech that get 90% of the play time.
I go through about 20ml of 4mg nic juice a day... (mostly DIY).

I've mentioned sub-ohm in a few of my earlier forum posts, and either threw out a disclaimer or was thrown one. For some reason I think I worded this one intelligently enough to get away with leaving one out ;)

So far I haven't bothered with a 26650 device; I was on the fence about it until I did my research and found out that the Sony isn't "really" a 50A continuous rated battery. I currently have a fleet of VTC5s and don't mind swapping them out frequently, so the mAh aspect of the bigger batteries hasn't swayed me over yet. I have been playing around with larger diameter coils though (currently loving 5/32") so the increased build space could provide some benefit I suppose.

Regarding one of your earlier questions in the thread, I run some single-coil and some dual-coil setups. All in RDAs/RTAs. I haven't taken the genesis plunge just yet. I had a dry hit on ss mesh early in my vape experience and won't touch the stuff now!

For me it's high wattage and no looking back. That means sub ohm on my mechs around .3, and 30 watts on my DNA30. I use high resistance coils on the DNA cause running the higher voltage seems to improve the vape. But yeah, I use drippers everywhere, never thought I would. I'll be dripping into my RDA while I'm walking down the street.

I have heard forever that PG would carry more flavor, and lots of store bought juices and DIY reflect that... but things have changed lately.

I'll have to go back and find the comments in DIY sub forums that talk about the an analysis of why the opposite is a valid case.

Also if you look at most juice vendors today, making new juices, they are heavy on VG.
I think the VG trend is due to popularity of sub ohming, (and the fact that lots of folks have reactions to PG) but got to admit they are good tasting juices.

In my DIY juices today, i virtually eliminate PG.

I can only base my observations on my very own experiences. I mainly "DIY" from flavor concentrates. If I use a lot of VG, the flavor is very muted compared to... say a 50/50 mix. Seems I have to experiment/look into this more.

Anyone else out there that just can't bring themselves to jump over one measly ohm? FWIW I only use mechs, I've stocked up for the vapeocalypse and don't want to spend $$$ on a DNA or similar device that "may" provide a similar vape using > 1 ohm coils.

On a mech I'm happy with my Kayfuns around .6-.8 ohm and dual coil drippers around .4-.6 ohm (depending on wire) any higher resistance and it starts getting too anemic to be enjoyable, especially as the battery wears down.

With a good quality regulated device I'm perfectly happy with higher resistance coils powered at higher voltages, but then it becomes more of a size issue. A tube mod with a decent chip like the DNA30 is huge compared to an 18500 or even 18650 mech and I'm very picky about dimensions.

So I don't really have anything against high resistance coils, but vaping high resistance coils would mean a big change to all my vaping gear and habits, for really no advantage at all. That's why I stick with mechs + subohm builds.

This isn't exactly the thread/post that i was looking for but it gives a nice rounded analysis of the differences between PG/VG....
Its a short thread but great info.
Basically, VG is thicker, and it takes flavor concentrate molecules longer to saturate through the VG... more steeping needed.
Also PG tends to vaporize faster leaving a drier feeling, but TH is based on nic levels.

I'm running .9 ohm on the Kayfuns and a .7 ohm single coil on the RDA and am very pleased.

On the RDA I wanted more kick, more smoke, more flavor and comparable battery life as to what I get in the KFL+.
Mission accomplished with a .7 to .9 single coil build on the RDA.

Recently tried a 1.3 on the R91 for the Vamo and it was lame in comparison, but vapeable if needed.

yeah; RDA, RBA, RDA-tank, etc etc not to mention Genesis which falls in the RBA column,,, there are a lot of variables here.

I find Kayfun style can't handle sub .5 ohms very well; ymmv, and for ultra low, seems to me you have to go with drippers that have lots of air, and wick close to juice source. There are under-coil air sourced atomizers too.

Because sub ohms has such a range down from below 1.0 ohms, there's plenty of room to find the sweet spot.

Don't be surprised if you start going lower ... i find its all about wicking and air.

People are finally starting to realize that it's not so much a case of VG being a poor flavour carrier, it's just a different flavour carrier.

PG definitely provides a sharper flavour but VG produces a richer flavour that works really well with certain juices, dessert blends in particular.

To stray a little more on topic though, I've been vaping sub .4ohm builds on mechs for a couple years now but a DNA30 with a ~1ohm build has pretty much taken over as my daily vape.

I agree. Its not just a smoother TH but a smoother flavor as well.

I know many awesome vapers who love 1.+ ohms micro coils in just about everything. I'm just not ready to optimize that range yet ... when its time to recoil something, I just can't bring myself to do it...lol.

All about the flavor and throat hit for me. The higher ohm set ups just lack IMO unless they are on a regulated device.

The problem with this theory is that once you get below about .6Ω, you need so much air flow that the flavor is actually diluted. There is a point of diminishing returns when flavor is the primary goal. Heat helps the flavor bloom (in many cases), but it also gets to hot to vape without maximizing air flow which defeats the purpose of jacking up the heat to help the flavor bloom.

I agree, well said...
but for me I can get great flavor as low as .4 ohms in most single coil drip atomizers, but so far with dual coil atomizers below .4, with the exception so far of the Origen, the flavor is diluted.

as you stated, those factors (heat/air), and include wicking, all combine (in different ways inherent in different designs) to either make a great vape... or not so great.

And of course there's trade offs.

It helps to try a bunch of different atomizers, and then again you have to experiment with different ways of setting each up... can be time consuming to say the least.
Once i get something i like or love, I stick with it but I'm always looking around...

http://www.e-cigarette-forum.com/forum/diy-e-liquid/579638-flavouring-90-100-pg-questions.html

here's another slightly OT but very interesting note on using VG over PG:

from we2rcool; a very expert DIY'er...
"VG definitely does NOT minimize flavor! Because of it's thickness/viscosity, it takes a bit longer for flavors to 'come through' (that's how the rumor got started). PG has a definite musty flavor that competes with flavor. Once you've done "side by sides" (that have steeped adequately), you'll always need a bit more flavor with the PG.

VG ROCKS! We prefer it diluted by 20%."

[we2rcool dilutes his VG nic liq. with 10%distilled water, and 10% of a 9%saline solution.]
