You might want to look at the 1.8 ohm Triton coils (and yes, they can be used in the Atlantis). Supposedly they are perfect for mouth to lung hits. All of the Aspire coils are single vertical coils. When looking at the Aspire coils for the Atlantis and the Triton (they are interchangeable), they come in 0.3, 0.4, 0.5, 1.0 and 1.8 ohm.Because I am still glued to my little Kanger Protanks and have not tried the Atlantis yet, can you tell me what's in it? Bottom horizontal, verticals, multiple coils... 2-ohm, 0.5-ohms? Puffer? Cloud maker?
