I vaped with the original Aerotank, the V2, and the Aerotank Mini, which was by far my favorite. I finally passed my beloved Aerotank Mini over to my son, and I still have partial boxes of KPT single and enclosed dual coils. If memory serves, either coil will work with both Aerotanks; it was the mini Protank 2 that won't work with the dual coils.
I've never tried this, Tam, but the old Kanger dual coils work with Subtanks, too. They come in 0.8 and 1.0 for SubOhm vaping; I used the 1.5Ohm with my Aerotanks.
