I have only one atty using it right now. they are 2 mm id and perhaps 7 wraps. 0.07 ohms (duals)
Well what should i say... for a long time i thought all this tc nonsense is a hoax, a marketing thing. I tried a lot of devices & wires over the past years and was really disappointed. I never got a consistend tc vape no matter what atty or mod. I own a Dicodes Dani V2+ and an Evic VTC Mini and both didnt do it for me. I tried Ni200, Ti, Resistherm and SS430, SS316L and SS403... so I kind of gave up on tc.
And then I stumbled across some wire i've never heard about while ordering some other stuff off of zivipf... NiFe48. I did a quick research on ecf and found this thread and ordered a spool of NiFe48 0.4mm just to make sure this doesn't work for me either. What should I say... I was wrong. Damn wrong. This wire is freaking awesome! It works like a charm on both my Dicodes and my Evic. I tried it with several RDAs and RTAs and no matter it just delivers. So if you are still not satisfied with Ti,Ni or SS give NiFe48 a try!
TL;DR NiFe48 kicks ...!

I gave up on everything too, except SS316L. Haven't tried exotics like resitherm or the non standard S.S.
I found that cheaper TC mods only had a prayer of working well on builds greater than .5Ω, and higher was better. Tough to do with 316, especially dual. Then I allowed myself the luxury of some DNA devices. Night and DAY.
I have a question for you all. I have seen sites selling SS316L wire, advising not to glow the wire due to the potential for oxides. Did I miss some news? Is 316L unsafe to dry burn? Maybe I just forgot..
IMHO it is no "unsafer" than dryburning kanthal. We need these oxides to form an insulating barrier to keep the coil from becoming near dead short when winding contact coils.
Also imho contact coils are really not needed for tc mods and you can switch to spaced coils and have just as good of a vape as compared to contact coils. To me it reduces the likelihood of coil crud from bridging all the wraps and needing to dryburn to get rid of the crud.

Thanks for reaffirming what I already thought on dry burning. Yeah, I don't bother with contact coils in TC. Too many problems. I WRAP them as contact, but then I use an exacto to get just enough gap between them. Seems to work very well.
I use basically the same method but I space them way pbusardo does. I basically grab the ends of the coils spread it then I squeeze it together voila perfectly spaced coil.
I bought SS430 from CrazyWire because I hoped that the reduced nickel content could be good for my sensitivity to it. Not at all. Now I'm using it for my wife on a VCT Mini (DNA200, 75 and an Apollo Reliant for me) and I have the same problem, I needed to raise the TCR value to get acceptable vapor production.
But reading this made me think: maybe I *could* use SS430 if this is not the right wire. Any more insight on this. Any proven SS430 source? Thanks.
Here's where many of us got SS430. 200' of 28AWG for ten bucks ain't bad.

Thanks GeorgeS. I've read past posts and they all seem to confirm that CrazyWire's SS430 is not what it says it is. TCR doesn't like, after all. I just ordered from Unkamen. I really, really would like to avoid working with Titanium and its springiness...
This SS430 is nickel free:

I drill twist two strands of (Unkamen's) 28 together, it's pretty much all I use lately. They ship worldwide.
As far as CW's 430, I'd say it's 430 just not the same and not the same TCR. It works well for me two.

Unkamens 430 is a bit springy, I lightly torch it prior to coiling then it's fine.
When Unkamen's 430 arrives I'll report back. In case it triggers my sensitivity... I'll be available to send it to anyone willing to pay for shipping. I ordered the 200 feet spool so... somebody might be interested. In Europe at least. Cross your fingers for me, though, pretty please. 
Liiiiiight torch, only... a lighter to just heat it a bit. If you get it even to dull orange, it tends to get brittle, in my experience.

I agree, lightly torch 430ss before coiling. Thing is, once you dryburn it the first time it becomes pretty weak and flimsy. Kinda difficult to keep from deforming the coil if wicking with rayon where heavier wicking density is required.
I'm with @dwcraig1 , twisted pairs or triples are better. It helps to stiffen things up some. Love the stuff.
From my experience the Temco TI wire is not springy. (very easy to work with)
I account for the springyness of Unkamen by using a 0.5mm smaller jig than I want the final coil to turn into. It seems at ~3mm finished ID SS430 is ~0.1 ohms per winding.
I just lightly heat the wire to dull red with a bic lighter before winding. It puts nice looking blue/purple oxide layer on the wire and wraps almost as easy as kanthal.
Wow... I ordered on the 3rd, it shipped today.When Unkamen's 430 arrives I'll report back. In case it triggers my sensitivity... I'll be available to send it to anyone willing to pay for shipping.

Ok, I got my SS430 from Unkamen. I'm using it, twisted, on three different mods (VT75+Calix, VTC Mini+Hurricane, Apollo Reliant+Hadaly), three different eliquids. TC is perfect, no sensitivity at all.
I am now sure that whatever CrazyWire sold me as SS430 was NOT in fact SS430. I am quite upset with them.
Twisted SS430 is quite springy, but at least is dry burnable with no worries. Next time I'll try to lightly flame it as suggested (or anneal it before winding, by connecting the wire to the two posts in an atomizer, as I did with titanium).
