advantage of a dual coil clearomizer tank?

[VictorViper]

I'm curious about this myself. Looks like opinions and preferences are all over the place so I guess a side-by-side is in order. I'm a total newbie to vaping and haven't really experienced enough to rant or rave about technical shortcomings or merits, but flavour and throat hit are immediate and (at least subjectively) tangible, so I'll edit this post in a little bit with some early impressions. I've got a fresh Protank (2.5 ohm) and a couple of iClear 16s to try out. No time like the present!

[EDIT] Shoot me. I had a few nice paragraphs all written out... On my iPhone. Hit submit aaaaaaand you are not logged in say goodbye to your work, give your thumbs my best.

The super condensed version based on super condensed side-by-side tests using an itaste MVP:

iClear: Good smoke. Big flavour. Less satisfying throat hit. Too thick/rich for my tastes. Good as a treat, but not for regular vaping.

Feather in the cap: great draw resistance. Cigarette-like inhales are a nice creature comfort (I'm only 2 weeks into quitting tobacco).

ProTank Good Smoke. VERY sensitive to voltage changes. At the sweet spot (for me it was 4.1v with a short cook), has excellent throat hit with just the right amount of flavour coming through. Natural transition coming from the Tabac BCC (Kanger T3) and a clear upgrade.

Gripe on the side: Has a "breathy" draw and imparts a sterile, clinical taste. Hopeful and confident that will change as it's fresh out of the box and hasn't had a chance to get "seasoned" yet.

Yes indeed it does use more battery. I just got the Smoketech SID last week and have been vaping between 7 and 8 watts with my 1.5s and 2 and 3 ohm cartos. You have to have those cartos filled nice and saturated. I got the ones with 1mm hole already in them so what I do is take my punch or whatever you have like a nail and I widen the hole just a lil then punch another hole on the other side and I use 80/20 pg vg or higher like 90. It never floods on me with those 2 holes the stock 1mm modified a lil bigger and another one punched not a full punch just were it makes a hole which I would say 1 to 1.5mm maybe 2mm. On the first fill and priming I drop 30 to 35 drops and this is on 35mm length cartos for tanks and will let it soak in until I see some weeping out of the punched holes then I will put it in my tank put some juice in and do some primer puffs about 12 to 15 you will see bubbles from the hole. You will know its full when it starts to not make bubbles and gets a lil bit of a gargle not a loud stronger gargle and I let it set for 15 mins. Then vape away and it works great. I do want to get some single coils to try. That will be my next purchase. How do you compare and think about the single vs duals Mad Scientist?

That's a great question and the answer is always "it depends." A single that's able to efficiently wick at high wattages is the same as a dual, really. What's going on with the dual conceptually, I think, is more wick surface area exposed to the heat of a coil. More wick surface area generally equals better vape because the wicks are just never perfect so there's only so much juice in a given area of wick and a wick can only feed so much juice per area while heating. On the other hand, I can say for sure that if you have a wicking material and set up that just vapes like a freight train, even (or really especially) at high wattages, more coil will not get you better perceivable vape experience. Once you get there, "more" is very hard to discern.

One of my many never ending quests for the holy grail of vaping includes getting a BCC (EVOD present favorite) set up just right and once the wick is just the right diameter and coil tightness just on the edge of gurgling but not getting there with the particular juice in it, and it will feed the coil while heating producing a rich, flavorful vape for as long as you can draw (or just about forever, really, it will just keep wicking like a champ as long as there is still some liquid in the tank if it weren't for a battery timeout), there is no way a second coil would add any perceivable "more."
