I have been reading up some and was trying to find an optimal build for my Sony vtc5
Am I correct that using 28ga+ wire is more efficient than 26ga or lower?

Touching back on single cell mech builds..

that depends on what ohms you set the coil to.... if both coils are set to the same ohms, then the thinner wire will "use" less amps, but the difference is small when comparing wire in that range. If you were to say use 28 compared to 22, then there is a huge difference in amp draw to get the same "heat"... thus quicker battery drain with the 22 ga.
I would lose surface area then though right? Maybe parralel coils?
Two coils of the exact same resistance will draw the exact same current regardless of the gauge of the wire. The heavier wire will take longer to ramp up and produce vapor, so you will have to keep the button pushed longer, and your battery will drain faster.
I switched to a parallel build for my mech and works very well. I use 26ga parallel single coil, I believe 28ga dual coil would work.
If you have two lengths of wire with one twice the thickness of the other, the thicker wire will have twice the surface area but four times the mass. See Pi does have a real world use!
Thin wire is way more efficient but needs to be used in parallel on a mech to keep the resistance down.
I can't work with 28 guage, way too flimsy.

Start simple and work your way up. Yes, this applies to coils but also, you know, life. Good luck though with your endeavors. There are many folks who enjoy two coils for more surface area, when wrapping one wire that's higher mass or twisted or exotic wires will give you a similar surface area but less mass, as stated above. Were it me, I would start with one coil then two, to see how you enjoy the differences in each? It's just a thought....

So twisting like a 26 and a 30? I'm confused. Building I have no issues I can make any coil at this point just trying to find a sweet spot for the single cell im used to my 2 cell regulated mods
I agree with this. I call it the K.I.S.S. Principle. (Keep It Simple, Stupid)
In my personal experience, when building coils for a mech the less mass the better: Less ramp up time and less drain on the battery. I consider the factor of surface area to be over-stated when comparing it against ramp up time and drain on the battery on a mech. YMMV. I've vaped on many exotic coils (used to work in a vape shop) and never experienced any benefits over using simple compressed coils on a mech.
I use 26 gauge Kanthal. Two 1.2 ohm simple compressed coils (0.6 ohm combined) gives me a great vape on a mech, gives me some margin of safety over and above the continuous discharge rate (Samsung30Q 20A 3000 mAh), and is less draining on the battery.
1.0 ohm = 4.2 amp draw
0.9 ohm = 4.6 amp draw
0.8 ohm = 5.2 amp draw
0.7 ohms = 6 amp draw
0.6 ohms = 7 amp draw
0.5 ohms = 8.4 amp draw
0.4 ohms = 10.5 amp draw
0.3 ohms = 14.0 amp draw
0.2 ohms = 21.0 amp draw
0.1 ohms = 42.0 amp draw
0.0 ohms = dead short = battery goes into thermal runaway
Everyone is free to set their own safety parameters, and I can only say what mine are.
I try to never exceed 50% of the CDR (continuous discharge rating) of a fully charged battery (4.2v). So with a 20A batteries, that would be 10A. The above Ohm's Law Calculator tells me that a .4 ohm build is as low as I would want to use.
The reason that I place a 50% limit is because as a battery ages the mAh of the battery degrades, as the mAh degrades so does the batteries c rating (amp limit). So down the road, your 20A battery may only be a 10A battery.
Solid pretty much what I'm narrowing down is a .3-.6 for myself personall.y just don't know how some people throw crazy clouds off one cell
Throwing clouds really has nothing to due to the number of cells
From what I have observed is those "cloud chasers" are using coils under 0.2 ohm. Yeah, a lot of clouds but they are pushing a single cell beyond the CDR. They usually say I've been doing that for months/years and nothing bad has happened yet. Keyword: Yet.
The CDR isn't a suggestion.
It's the safe operating limit of the cell.
I've had a battery explode in a mech before. That was back when I was naive to battery safety. I'm not being a fear mongerer, I offer information based from my experience, research, and knowledge.

Yep.
I can get a nice warm Vape with plenty of plumage on a 0.2Ω build when I'm on one of my tubes, it's all about the build. But if I really want to be obnoxious and blow insane plumage I'm on my HOG with triple fused claptons @ around 0.4Ω.
There's no real reason to abuse your batteries and go beyond the CDR
So I figured out something haha a starting point. Four twisted 28g wires claptoned adds tons of vapor
You,can't be telling me a single cell mech powers 3 claptons!?!? Mine can barely power two :-(Yep.

And I bought brand new Sony batteries through my buddy that owns a vape shop!!!! Maybe it's the connection or the button...
