I'm a fan of the Flak 2.0s as well: good style and great fit.Mine is to maybe stop buying so many Flak 2.0's but I love the frame so much, even though I know no one cares because they aren't limited or rare, but they just work for me and are so functional.
I would like to pick up a pair of carbon X-Metals and a pair of the Shift Collection frames, either in the Radar EV or the Radarlocks. And get some different Prizm lenses, my goal is to eventually own every color they make.
