May as well keep up the theme of Juliet Plasma Fire. Recently picked these up locally. My second pair of X-metals. Love the plasma finish but I'm not crazy about fire lenses. They're great to look at, but not awesome to look through. I'm going to try them out for a while to see if I can learn to love them, maybe change them to emerald. Still learning about generations, but 4th gen has no marks of any kind on the stems right?
