Ok so it's a couple of months after the last post in this thread and I'm wondering if anyone has actually tried the Protank 2 type coil heads in an Evod atomizer? The reason I'm wondering about this is that the Protank coil heads are 26 mm in height but the Evod ones I found are only 22 mm high! Therefore I don't see how the Protank coils will fit into the Evod atomizer unless you cut the height of the chimney down to 22 mm to match the Evod specs? So if anyone has figured this mystery out, please tell us about it...tia thanks in advance.
