I just started collecting about a month ago. Only have 4 pairs so far, but looking to score several more in the not so distant future. These are the 4 pairs I have so far. They are nothing special, but it's a start. 1st purchase was flat black polarized fuel cells. 2nd was polished black crankcase. 3rd was polished white gascans. And most recently I got my custom batwolfs, polished black with gold ghost text, team vegas gold icons, and dark bronze lenses I think I need to invest in a new camera... hard to take good pictures on my phone.
