I am looking for a clearomizer or cartomizer/atomizers that work well with the GLV. I don't care for the Boge style, but like the clearomizer but I need a clearomizer that the mouthpiece screws on not just press fits. I also need an atomizer that can be used with bottom feeding. I have no idea how to hook it up for bottom or top feeding, what kind of atomizer I need for that. thank you.
