I've been rocking the Arctic for awhile now. It's a great tank. I run mine at 40ish watts most of the time when its on my IPV Mini2. Then other times its on a SMPL mech mod at 75ish watts (
you have to file down the negative 510 threads for the Arctic to work on a hybrid mech mod, don't blow shit up please).
I don't notice the sweet spot you (and others) have mentioned. With the 0.2 coils on a mech it's an angry little booger and it gets hot fast
but its a great vape as long as I don't chain vape it. On a regulated mod I really like it around 40-50W but I'll try playing around at 60-70 tomorrow (because research). I DIY and my juice is 80VG minimum, maybe that is causing a difference in my wattage preference. My juice is not over-flavored, but it's definitely not lightly flavored either. Some mixes rock out in the Arctic and some are muted. It's not bad when it comes to flavor but its not at the level of a (properly setup) RTA either. For me, the convenience of prefab coils, the ability to lay on its side and a little less flavor trumps the headaches of the RTA by a mile though. For the Arctic, I think I like the 0.5 coils better but maybe my 0.2s were a bad batch. The 0.2s taste a little funky.
Did I mention that an Arctic on a IPV Mini2 is the shit? If I had to leave the house with one mod and atty right now... that would be the combo. Fits in my hand nicely and fucks my face off.
My Super Tank will be here tomorrow though... Let the games begin.
