Old dog, stuck in my ways. still using Subtank plus, with the mini rba. I prefer to keep it simple, single coil. Still using Kanthal wire. Recently broke my last extra glass tube. I need a rebuildable, tank. L8ve the 7ml capacity. I don't want to be stick buying premade coils if possible. Whats new out there that will meet my simple need? Any help is greatly appreciated. Fyi, I have seen the baby beast versions, is there an the deck for any of those? Help please, so outta the loop.
