Took a look at it yesterday and played with it to both extents to see how much difference it makes.
One note of caution for other extremists: Setting the FOV affects the size of the Clipboard, too. Take note where the + sign on the Clipboard is located since it will shrink unreadable if you set the FOV to the max value. I'm not saying the max were unusable for those who like a fish eye view, just reminding that it affects everything that has a set location in the virtual 3D cockpit and its surroundings.
