Another place to looks for specialty coils is Advanced vape Supply Advanced Vape Supply. Their quality is quite good, and they specialize in SS coils. The advantage being you can use them in power/watts mode or TC if you ever go that way. There are also some folks around here who will also build for you. One guy I found very nice to work with and excellent CS was @B_D_Builders . You can PM if you want to reach him
