Any lightweight replacements out there, FAL was discontinued -- any other companies make any?

Thanks

 

Optic Armor has optical grade polycarbonate windows with anti-scratch coatings similar to that available for your eye glasses. I've never installed one but have seen it on a track car, it looked pretty distorsion free. And the anti-scratch coatings work fairly well unless you drop your glasses on the ground 10 times a day like I do.
