Of course with Oakley, styles come and styles go but what do you guys think makes a certain frame style that "keeper/collector" pair? Obviously some are more worth collecting than others but what do you consider when making a style the official shelf addition or thinking that you need to get more variations of that frame style? I always find this interesting because there seems to be a list of "must haves" that are no longer available, some are great and some aren't (in my opinion). Is it just because the style is discontinued or did something about that model in particular intrigue Oakley owners? And what do you guys think will be the next "must have" styles for collecting or adding to your stash?
