Golden Greek "Proteus" serial number reservation list was begun in Sept 2013.
However, the Evolv DNA 40 (40 W), was first to market; released 2014.

Thank you! Wonder how I manged not to hear about it.
Because at the time TC mods were expensive. DNA 40 devices were around (from what I remember) $200. Plus TC was sort of niche market, you had to use nickel and you only had 40 watts to work with. Now we have much better wire and 250 watts to work with.
Thank you! I see. That's why I didn't see it in online shops where I live. There were only 2-3 back then, now 3-4.
Still... it's not easy to have missed TC by late last year.
Hell, I started in with the D2 and Sig75 by what had to be mid Summer '15 at the latest. TC had come down to $50 and $70 by then... woot, bargain time.
SS TC as standard was still a ways off though.
Using good old kanthal in my Crown RBA now. Can't say I miss TC.
I didn't use temp control until I got my dna 200 and some stainless wire. NI200 and ti1 imo is just too
hard to work with, ss is just as easy, if not easier, as kanthal to work with. Right now I've got dual coil 26 gauge ss316l coil in my griffin using tc and the vape is great, tc usually keeps it around 50-75 watts.I didn't use temp control until I got my dna 200 and some stainless wire.

SS wire is nice yes, but the resistance is too low I think. Juice is expensive. Vaping with a 1.3 Ohm coil at 13 watts now, and it's nice to see the juice last a bit. Could try 30G SS316 though, but TC coils need to be spaced I have read, so I'm afraid it wouldn't fit.

I forget! Ohm doesn't matter much on a regulated device. Next coil will be SS.
SS greatly prefers to be spaced, even just lightly. No idea why, but it actually make simple coil life easier.
The spaced or contact coil when it comes to TC usually boils down to the question of is the metal used in the coil able to create/generate a reliable electrically insulating oxide layer or not?
While many of the metals used in TC can be dry burned to create the required insulating oxide layer in some cases the layer will become compromised when the user is jolting the coil while wicking it and unknowingly leaving hot spots in the coil in the process.
With the added data point that spaced coils may "gunk up" slower than contact coils there are plenty of argument for using simple spaced coils in a TC application.

Mostly, I'm just lazy.
Roll, stretch, press... Bob's your uncle.
Naturally... I now own a variety of tweezers I don't particularly need, especially the ceramics.
Resistance doesn't matter, especially in TC. I build a spaced coil and then stretch it out learned that from Pbusardo.
That may not be exactly true.
To high of a resistance and the mod may refuse to TC regulate the coil - automatically kicking the user into power mode. To low of a resistance and the TC regulation might be iffy at best.
Recall that to guesstimate the coil temperature the mod needs to read the COLD resistance of the coil and then use the TCR value of the wire used in the coil to calculate the resistance of the temperature set point.
Given the same TCR wire a coil with a 0.25ohm cold resistance will change 1/2 as much as a coil with 0.50ohm cold resistance. The higher resistance coil offers twice the granularity as the lower resistance coil.
So you see, base resistance in TC mode can matter. How much is dependent of the MOD and TCR of the wire used.
Single, spaced coils do work well for TC. Works fine with my SS Claptons too. In many ways it's an improvement over plain wattage, as the preheat can be adjusted to you don't have that few second delay in heating that much metal, and then maintaining the temp throughout the draw, so you don't get that too hot at the end of a long draw.
I think TC is whatever you want to make it be. If you prefer a smoother, stable vape throughout the draw it's a terrific solution. Other folks prefer power mode as well as building with Kanthal, and there's nothing wrong with that either. I did it for some time before moving over to all SS builds. And while you can get nice clouds, you're not going to win a cloud competition with TC, so there is that.
