That is an excellent point, CC. Seems that a lot of the sub0hm setups have TC drop in coils, though not every single one of them, and I did kind of wonder why smok doesn't.
To be fair, I don't own that mod, but it was kind of comforting that when I actually bought the steampunk Tesla 120 nano "starter kit" it came with an RTDA topper, the arrow. Seemed likely that they were expecting users who purchased it to be rebuilding right away, LOL.
I vaped the Arrow briefly, it was not to my MTL tastes, so I was able to give it away, but I've found the steampunk does TC pretty well (as best as I can tell, I mean, it seems to just... work, when given the correct parameters on the right coil, I'm not testing the temp or anything....)
I have a silver one I just might break out of the box if I can get my Vandy Vape Beserker to work well without leaking, it seems just as reasonable as buying another mod just now, as long as I can get it not leaking all over the place, and etc.... I am protective towards my steampunks, LOL.
