I would head down to a west marine or Bass Pro and give the costa's a look and see what frames you like, but definitley buy them on ebay. Big time savings. Also take a look at this page...

On the right and bottom it has the lens color options and goes into what they are best for. I have the green mirrors, which were great for the back country in FL but I think I might do better with something else up here.
