Maybe sub-ohm vaping and blowing big clouds isn't for you, it's definitely not for me.
Doesn't Wire size play a Role in all this?
When I do a "What If" for .8 Ohms using a Single Coil of Kanthal A1 26ga, I get a Heat Flux @ 15W of 166 mW/mm by this calculator.

But when I do the same .8 Ohms /15W using 28ga, I get 333 mW/mm
I know that Heat Flux is just a "Guideline" value. But Shouldn't a Person see a Hotter vape on the 28ga for these Two Builds at the Same Ohms/Watts?
1: Yes wire size plays a role
2: Heat flux is not just a 'guideline value' ; if you look at the colored flame thing next to heat flux, you might notice that for low values, it is blue, for high values it is more red; around 200, it is green.
3: Yes you see a hotter vape on the 28 gauge than the 26 gauge; 333 mW/mm2 is hotter than 166 mW/mm2
I think I have to build some higher resistance coils as some of you suggested. The materials are on the way. I have only tried 0.5 and 1.2 ohm pre-made atomizers up til now. I think that a 26 gauge, 6 turns or more, with even spacing (for vg liquid) should be good. I use VG 100% with some Capella flavors
I was used to vaping 22mg nicotine, but this is too ferocious for these sub ohm systems, and certainly gets the old heart racing faster.
What I simply do not understand is people showing these you tube videos with 25 watts and 0.5 ohm being a sweet spot on the Kanger pre-made coils, when it's like a furnace for me.
As for someone mentioning that there are different ways to "lung inhale" this is quite confusing. I understand there is a potential of speed/rate and quantity of inhale difference. I do not see how there's another "way" to lung inhale? Am i missing out on something?
Yeah... The Reason I used the word "Guideline" when referring to the calculated Heat Flux is because Actual Temperature at the Coil depends on more Variables that just Wire Type/Geometry.
Heat Exchange via Wicking comes to mind.
But the Reason I mentioned Heat Flux is that I Don't build Much. I'm kinda Stuck in my Happy Rut. But when I see an Order of Magnitude difference between these 2 Gauges of Kanthal for the Heat Flux, I scratch my head and Wonder if a person like the OP would be Happier with trying a different gauge of Wire?

I'm not sure. What exactly do you want to achieve?
Here's what I use to make coils couldn't be any easier. http://www.amazon.com/Artistic-Wire...1427839577&sr=8-1&keywords=Deluxe+wire+winder
Do some searches on ECF for some video information on making and installing coils/wicks with the Wire Gizmo.
For the perfect coils for the Kayfun I took an regular old wire coat hanger and made another mandril that was the perfect size coils.
More power means greater and faster vapor production, crackling is audible evidence of this almost explosive vapor production. To me it's a beautiful sound.
Reminds me of this time on the Trường Sơn trail back in '73.....
