Actually, I have done a 1.8 ohm BVC build on the Triton RTA. I used 28 gauge Kanthal wrapped around a 2.0 mm drill bit. Damn near exact performance of the 1.8 ohm factory coils. It did gurgle a bit in the beginning, but it smoothed out nicely after awhile because the cotton finally swelled up enough with the juice. Haven' had a dry hit, even chain vaping it. Actually all my builds so far gurgle in the beginning. I've tried using more cotton, wrapped more tightly around the coil, but then it's to tight and the juice won't wick properly and I get dry hits.
I might try using 26 gauge with more wraps next time to see how it turns out.
Maybe I will try the triton RTA one last try, I admit I did only try the coil that came with the kit, and normally I use compressed coils in my RBA's, so I will give it one more go, but not a big deal if still not great, as finding the Anyvape Atlantis RBA is working good with it, apart from it does start to leak a bit once the tank gets low.
