lol, I run a tank called the silo beast from beyond vape, it holds 5ml, has top topfill and it takes atlantis and triton coils. I use the 0.4 ohm Triton coils in it, - they are stainless steel, so I can run them in either TC or power mode. Whats nice is that they only neeed 40-45w. So I can get really good battery life out of them. They also have a 0.3 ohm coil that takes 50-60w. Or there is a third party Clapton for it from Atom VAPES. There is also a 0.2 atlantis that needs about 80w
I normally build, but its nice to have a good reliable easy to find coil for traveling. a triton or atlantis coil can be found anywhere.- literally.
