Just got an '09 C300 black on black. Thinking about 35% around and 20% rear windshield. What do you guys think? Hoping I won't get pulled over for it after it's been done.

edit: or 35% driver/passenger. 25% rear windows. 20% rear windshield?

 

I wanted to get some pointers on window tint for my 2010 c300 black on black. I live in San Francisco, California and was thinking of going with 35% all around a nothing on the windshield although the legal limit on the front is 70%. This is the first time I tint a car and was hoping to get some help. Any suggestions?
