I've decided to buy a pair of oakleys... currently torn between A wires, big square, and crosshair. However, my main problem is which lenses to go for? I've heard gold lenses are good but I think I'd look a bit of a pratt with gold lenses! I like the look of "black iridium", but are these too dark? what about "dark grey" or VR28s which I've been reading about on here? I think I'd only really wear them on sunny days so maybe dark ones would be ok? Currently doing my PPL, but if I'm going to "invest" in an expensive pair, I'd like them to last through further training. Anyone got any advice?
