Yes and yes to the first set of questions. Thinner juice, especially with the .6 ohm coil, does help with dry hits, but there seems to be an annoying number of coils that just don't wick well without some tinkering. That being said, when they DO work right, they last a really long time. At least mine have. I don't notice much drop-off at all when the battery is getting low. All of a sudden I just won't be able to take a hit!
I would love to hear what your thermcouple testing turns up, and also a pic of that gorgeous marbled purple Penguin in the wild would be awesome!
How are you restricting air flow? Tape or something in the air flow hole?
I'm using a high technology method of Tape
I really wish they had made a nice slide adjustment there . This is the most I've enjoyed the device so far.
Even the answer Joyetech gave to ChefLance said that plugging the intake and no fire draw would help . Well to me that's them saying that there is a wicking issue. And if you wait until you get dry hits , then it's really too late because the cotton would already be scorched and tuff. I think this way a certain amount of air is now being used to help siphon the juice by restricting Intake.
Either way .. i'm just liking the new draw I'm getting by covering half , some other may not.
Now maybe 50/50 liquid would only reguire 1/3 intake covered? not sure but with adjustable air inlet you could mess around and see
That would be amazing if they made it adjustable! I think I would be fine with half intake. I put my finger over half and I liked the draw. On my last coil I would put my finger completely over the airflow hole and take a big no-fire draw to wet the wick, but it only lasted 2 or 3 hits before I had to do it again. Since my first coil burned out after ONE dry hit I am trying very hard to avoid dry hits. I keep meaning to fluff the cotton more in my last coil and try it again, but the one I am using right now is working so well I don't want to remove it to play with the other one, lol! I will do it at some point, though. I'm curious to see if I can get it to wick right!I'm using a high technology method of Tape

Yeh and I think you are right when you said way back that some coils are better than others. Or seem to be. And that would relate to assembly of the coil, i'm sure it's not always a consistent cotton wrap, some tighter than others. Affecting the siphoning. By restricting the intake it HAS to pull more siphon to the coil on each draw. it's just a matter now of regulating it as best as can . I was thinking of making up some tiny silicone plugs to vary the inlet size. And try that. And the matter of how long a coil lasts. Still unknown, but even if they don't last as long as we would like , at least give us some dry hit free life span. I'd be happy with that
We plan on using 50/50 unflavored so I have high hopes for coil longevity.
We could say that we both have a lot of patience . Yesterday I couldn't resist but I bought a silver one in Spain and for he will be here after 2 days Maybe I make the penquin with glittery myself? Hahaha Also I ordered 2 gourmet liquids from Halo to give it a try.I know, right?? I checked with Heaven Gifts and they said that the one I ordered from them would ship next week. I hope it's the same with Vapesourcing. I will feel better when they are on the way!
Let us know how it goes Mike .
By Joyetechs own answer inhaling keeps the coil primed. And if you stop and think about it, that's no simple thing to design for with so many variables. The thickness of the juice or how tightly the cotton is wound at factory etc. Too much siphoning and the coil floods , too little and you get dry hit. Adjustable airflow seems like would really help. And so far has with this last coil for me , most usage with not even a hint of bad hit yet. fingers crossed
On my 3rd tank now. (going on 5th day) .25 coil and 1/2 air intake covered. Hitting like a champ and no dry hits , 70/30 juice. Plenty of vapor (for me)
I wouldn't want to permanently inject anything into the tank. Kinda risky of clogging something up.
This simple piece of tape over the air intake has been working awesome for me. I have 2 separate tanks going now both with 1/2 air intake covered. One with the .25 coil , 70/30 juice and the .6 coil with 50/50 . And not 1 bad hit yet (the longest I've ever gone without one). Started the .25 on Aug 1st. I hope others get the same results. I'm super pleased so far.
I found some tiny smiley face stickers at the general store that can be placed over the Inlet and are not as bad to look at as tape.
I plan on blocking off the airflow from the bottom of the airflow chamber. I.e. remove the silicon plug that the coil sits in and plug the air channel with silicone from the bottom of the channel. Start about 5:40 into the video to see the plug coming out.
Once the silicon plug is out, to plug off half the air chamber from the bottom would be a piece of cake, as there is already a wall splitting that chamber in half. Heck you could probably stick a cotton wad in there as "proof of concept" before doing anything permanent. Anyway, this way you dont deter from the aesthetics of the outside.
I thought about just sticking a piece of tubing down the mouthpiece to restrict airflow, but doing it "after" the coil wouldnt help with creating a vacuum to pull juice into the coil, where restricting airflow "before" the coil would.

@mikepetro yes that looks like a plan that would work . For right now I'm just going to keep it simple and use what is working excellent for me. I'm also afraid to touch either of these coils now that they are going so well, don't want to curse it . 
I haven't been using mine regularly but when I do I only get a hot hit if I take two big hits back to back. Haven't changed the coil since I fluffed it and been through two tanks.
I do re-prime mine every couple hits or so and it seems to be working great. Very good flavor off the .25 and nice clouds. Running a 70/30 juice. I did notice that it was not as good when it was down to like 1.5-2 mls of juice. I would recommend, still, not letting it get too low. And re-priming. I'm enjoying it now that I figured it out and it is so handy and compact.
I was thinking of trying to restrict airflow, also but don't want to do anything permanent and don't want to put something in that will break down or something and gum things up. I'll keep thinking about it.
Thanks to the forum here and especially Tosarge for all the analysis and research.

Well it was a gathering of everyone's input that helped with the issue. And when you wrote to Joyetech their answer convinced me they are aware of it. They admit that Inhaled air is also what keeps the coil primed. It's just that the 'Fixed' amount of air 'Intake' is so loose that there isn't enough left to pull down and help siphon the coil.
If you gave the Inhaled air a factor of 10 and the Fixed Inlet a factor of 9 , that would leave a factor of 1 for priming. So if covering the Inlet a bit changes that factor to say 6 that would give you a 4 factor left to help siphon the coil.
Just using random numbers for example.
Almost all tanks have a inlet air adjustment feature ( at least most that I know of) and even the Cue Vapor device has 2 inlet air slots and they have silicone plugs , and they even mention how you can use one to make your draw tighter. (see below)
I'd like to see Joyetech do this in the future on the tanks. I am so pleased on how well this has been working for me. I've started a 3rd tank with half air slot closed. I like have the quick change flavor variety. These original 2 tanks are working excellent , I'm at the point of no longer worrying about a bad hit and now and I will be shocked when and if it does happen. For awhile there I was praying on each draw.
Day 7 now on these coils. No bad hits.
