I like the bugs to think that it is just a larger cousin drivng the thing they smash into, so the last thing they see is me wearing a nice, big and fecking ugly pair that I got from Paris Hilton last time she was in getting her brain topped up (took a total of 20 IQ points to fill it, too!)
NO, I jest (really!) - I use a pair of grey, polarised Bolle's with nice flat arms that have not the slightest effect on the ANR (or passive) of my Bose X. I have not had any trouble with the polarised lens - indeed I think depth and color perception is greatly improved. Granted you can get blocking of the image from any LCD, but only if you rotate your head 90 degrees in the coronal plane, and not even Linda Blair could do that..
I know a CFI who has a neat solution to the problem of the arms in the earpeice - just sits them on the bridge of the nose as usual, then rests the arms ON TOP of the ear cuffs. Looks a bit funny, but you can't beat experience, and he owns that.
