I haven't vaped the Triton 2, but Eskie is correct that there are lots of coils you can try. I think the current "standard" now is the N2, and its BVC coils, I have the N2 and I found, however, that my coils last far longer in a Kabuki-- we are talking days longer. I have no clue why but I do theorize that it could be, since I have the 2nd generation, the extra tank size plays a role. I was pretty confused about it at first, and even started pouring in the darkest, sweetest juice I possessed in order to TRY to kill it, and it wouldn't die. I'm pleased to have better coil life given the cost of the tank. I vape it at very low airflow but the airflow is supposedly part of the genius of the design-- so it may be that. I get decent coil life at about a weekish for my 1.6 and 1.8 coils, and the 0.7 coils last 4ever.... The Nautilus coils are pretty inexpensive, which is a plus. If you don't have crazy gunk factors (I do, I can only use max VG I'm PGsensitive) or run supremely sweet or dark juices in a Nautilus 2 tank, coil life can be extended.
With that said, all factory coils will die eventually. I get reuse (x1) by soaking my coils in very hot h20 overnight, then rinsing and drying, get another few days out of them that way, and I'm happy about it.
With all that said, if you haven't tried an RTA yet, it may be the answer for you, not the N2 or another MTL tank, but I unhesitatingly recommend the Kabuki. FT has clones that are way cheaper if you'd like to find out without that kind of investment, but my understanding is the clones don't QUITE match up to the original, but it might be an inexpensive experiment to try. I like the N2 tank quite a bit, and do use it, but I vastly prefer what I have on there now, and the extra coil life is offsetting the cost of the tank, certainly! Also has a lifetime warranty, which is super pleasant for someone like me, who breaks things, to have....
