I went with the clear lenses on my BD's, and then added the amber covers. That way I've got the option to go clear or amber, and I'm keeping the sandblasting confined mostly to some $10 replaceable covers in case they get worn or even cracked from rocks or knucklehead type stuff. That was one of the sales guys' recommendation at BD, and I like the logic. I've not taken the amber covers off since. I'm told that it's sort of obnoxious (blinding) on a night ride if the BD's are in your rearview mirror. So that means I get to lead which I like. The XL80's have a dimmer switch as well, also a cool feature. BD's can be rebuilt as well, another bonus. Very happy with mine, although it was basically impossible to score a deal on them.
