I got some Stringers with blue 580 lens and black frames. My schnoz doesn't let them get tight as I would like around my eyes, so I'm looking for a trade for another model of costas with 580 lens. Fathoms are my first pick. I think deep blue brine, and turbines might work too. Black frames only. Please post on here or PM me. I might be interested in other models too, so feel free to let me know what you have. Thanks
