New member and first post I've done so please bear with me!

Love my titanium XX's and have a number of replacement lenses from Keystone/Custom X-Metal/Exovista (or whoever they are at the moment - anybody know what's going on there? They seem to be selling off their lenses cheap on EBay at the mo'), but miss the polarised lenses I have on my Square Wire's and Crosshair's.

Been searching through the post with no luck for items about X-Metal XX's with a polarised lens.

Any advice on getting polarised lenses for XX's or even modifying another set to fit would be gratefully received - and apologies if this one's been done to death before!
