Llumar Air Blue 80 for the front windshield is also a good choice as well.

I have this on my car as well and people or cops notice it's there. It's light enough that even I would forget that I had a tint there since it's so light. Generally it would be hard to distinguish with your eye unless another of the same car without tint is there.

I use F1 Pinnacle for all the other windows.

 

I had Llumar Air Blue 80 on my previous car for the windshield, and all the other windows. It was great since I wanted a virtually tint-free look, but it was a little bit too light. The 50% and 80% windshield is perfect, IMO. Not dark at all.
