On my quest to find Half Wires, I stumbled here. My name is Kyle, and I have 3 pairs of Oakleys. First is a Ice Iridium Tightrope, a Red Iridium C-Wire, and my all time favorite Fire Iridium Half Wire (though a bit beat)! The Tightrope and C-Wire were online oakley vault purchases this year, starting my collection. All metal...so far!
