I have 5% all the way around and 20% covering the whole front. I live AL and have been lucky with the law. Very dark, can't back up at night without window down but the privacy and look are amazing. My opinion would be stay with one percentage all the way. 20% at least and you will have to look hard to see the difference. The windshield is your call. Full daylight for me and you cant see in. Different however risky with tickets. Good luck.
