Glass and Lexan Winshield Question

Im about to put in an order for your half doors, and am on the fence about a windshield. Just two questions-

1.- Are both windshields compatible with the polaris roof?
And
2.- How scratch resistant is the lexan? I had a plastic polaris 1/2 on my 800S and it scratched so easy. I like the look of the lexan, but am leary of not holding up.

Thanks for any info
