@Boden, glad I didn't give up on the original Ijoy Tornado, it has a few flaws but I've learnt how to deal with them, the biggest thing to get right is the wicking, now thats sorted I prefer this to the Nano, most won't and that's understandable but for the way I vape it's a power house.
I have just ordered the T6 deck for it, so I'm going to hold off on your suggested build until that arrives on Tuesday, I have that day off so that is definitely a build day ha.
So, I'm going to build Quad, 27g SS316L 10 wrap coils (20 wire wraps), that will be a total of 80 wraps in one deck, stacked coils, 2 on each side, that should be an interesting build

Will have to take some pictures of that ! I wouldn't put Claptons in this kind of build, you would need 200w to power it...
I'm not sure if I can fit 4mm inner diameter ones in there though but I will certainly give it a go, I think 3.5mm will probably be better.
