I think it depends on the type of flying you will be doing. I fly offshore and I tried Serengeti Drivers but found that the gradient lens was not good when a lot of reflection from the sun was coming off the sea. I instead love the pair of Serengettis I have which do not have the gradient lens. They are not polarised but they cut down on glare as good as polarised glasses. I have also found no problem looking at the screens with them.
However, using with a headset (especially as mine is an ANR set), means that I have to make sure that the headset and sits properly with the sunglasses on, as otherwise the ANR doesn't work so well.
I cannot remember the name of the model but the number is 6535.
Hope that helps?
