I have the same tank as you ares. But I've been using my Kanger Nano for some odd reason. I've also been using my isub tanks as well.
I've read that's a nice little TC mod you got there my friend. My Jelly slice has a temp control for nickel wire coils. I don't use them because I'm not very adept with TC control yet. I understand the concept and the reason for it. But Im not 100% comfortable with using nickel coils as of yet. So I stick with stainless steal.
I have decided to buy a kit to build my own coils or at least learn how to rewick them. I want a freakshow or Mephisto RDA so bad! So I hope to learn and that way I can save money on coils. They are pricey and I should learn so I can save even more dinero.
I don't have any problem with nickle and I have a nickel allergy. I thought it would affect me! If you are allergic TFV4 tank by SMOK has Titanium temp sensing coils. They are much more expensive than others but they have 3, 4, and 6 coil setups. They are great for tons of clouds if you are okay with going through juice like water. Some are 0.15ohms resistance. I love mine!
