i got 2 pairs of triple tail costas.. love them.. one is a wave 400 bluemirror/grey lens had them 8 years.. nose rubber finally fell out.. gotta send em off.. and a set of 580 vermillions. those are AWESOME for sight fishing... fish stand out like a neon sign with those vermillion lenses!
on a seperate but related note,
i saw some glasses called flying fisherman at icast.. the owner of the company took a money clip from his pocket and grinded it across the glass lens.. and there was absolutly no scratching. he asked me "can i try that on your costas?" i just laughed, but he had a good point. costas scratch easily. the ff's also have better color differentaition than costa.. blue was blue.. red was red. i was very impressed. he told me that costa has been tryin to buy him out for awhile now. i can see why. i might get some ff's next time.
