I'm the proud new owner of a Silver Bullet. I would like to make it as portable and durable as possible. I prefer cartomizers to atomizers, but am open to suggestion. I've been thinking about a small but wide bodied tank to use tiny carto's on that could still hold a night's worth of juice, but I haven't been able to find this. I'm thinking maybe it's just not functional? I've already gotten the smaller batteries with the kick for the most bang for my buck at the smaller body size. I'm basically looking for maximum durability and portability for my beastly SB. Any product and combination suggestions would be amazing. Thanks!
