Besides the new hinge tech, what are folks' thoughts on the actual glasses themselves? Have they sold rather well? In my somewhat simple mind, I am flipping a coin between a "Tincan" or a "Tincan Carbon", ... or should I not be? I have always liked full-framed glasses, but I also love my collection of Flak's. Go figure. Therefore, anything on the 'Foil I'd like as well. Thank, folks.
