I do not understand what you are asking. if you mean what the coil is. it is about the same. other than I got ripped off bad on some pre-made coils today. still about the same but these lasted like 5ml. they are pretty close. usually within .03 ohm if that is what you were asking. I am not sure joules is the same as watts. that is probably why the sxm takes less. it can't be that big a difference. it could be powerful plus is way more preheat than I have set on the dna. not sure why that is. it's strange. I would not think it is that big a difference. now I see what you were thinking but it is about the same ohms. I have no idea why it is that big a difference other than possibly the preheat. 43 is too much on a .25 coil on the sxm but I can push 80 on it on the dna. have no idea but I get what you were thinking.
Yeah - I was just wondering if when you lock in the resistance on the SXM it reads pretty much the same as the DNA. But if it is as close as you say it sounds like that idea is out the window. :-(
