I just got an innokin isub v tank. Tried kanthal, Stainless Steel coils, very disappointed. I pulled out an old Arctic tank from two years ago and It's better than what I just got. Any suggestions on a great tank, top fill preferably. I don't have to have all the bells and whistles, something with great flavor and a good amount of vapour of course. Arctic, Aspire Cleito, TFV4 ?????
