i agree. i sold all but one pair of 580g glasses. all 580p or smith chromapop. i must say i do love the only glass lens costas i have left as everyday glasses. when fishing though it is no question, 580p in amber. inshore or on the lake these are my go to lenses. i like the grey w/ mirror mid day as well. save the money, get 580p off ebay. the lifetime warranty is transferable and costa stands by it 10000000% i've sent stuff to daytona, fl (there home office) from kansas, louisiana and here in fl and everytime they come back faster than i had hoped. if they don't make a certain style they will upgrade you for free. i've had this happen twice.
