The reason I want to shop around is because Kanger heads suck, I've already proven that the whole wicking issue is a big myth, it's purely that half of their heads have coils that are wrapped around each other and burn because of that, or the opposite ends of the coils touch somewhere, and that on the other end if the problem spectrum, that half of the Spinner-type batteries out there are defective and output permenant higher voltages than the lowest of 3.3. All you do is soak the heads in water and the silica fluffs up like cotton and wicks like a breeze.
I guess I'm really looking to see where sells Kanger heads (preferably the t3, MOV reccomemded I try them) at higher than 3.0 resistence, as this should take care of the possibility that my battery is permenantly outputting above 3.3. It's safest to go with the highest resistence.
