I have 0 patience for making my own coils, so I just use either the subtank coils or the rba that comes with it that also comes with pre-built coils. Also, I'm pretty solidly in the istick camp for my main vape use and I wish the new kbox mini didn't use mean for it's firing power, though at the numbers I vape at, it really isn't an issue.
I vape a whole slew of different stuff, but I think my favorite is Gravity Mixing's Tesla or Apothocary tonic's Turkish Snow. I just tried some bombvapor's warp star though and it's trying to become my new champ liquid.
