Replying to Which goggles should i get?

i have the giro encore helmet and have a medium profile face. the last goggles i had got pulled by the helmet, had a gap between the helmet and goggle, and didn't quite fit my face right, so I'm gonna try to do this right, and ur advice could help. thanks

also, does a polarized lens help. i have polarized sunglasses, and wouldn't go back, but i'm hesitant to pay the extra money for the feature... the crowbars come polarized, and im kinda curious about them
