haha.. I remember entering a few banner options of my own back when it was being decided the first time...
The banner situation is a tough one, you can keep changing to keep things fresh.. but that's more work, and also stuffs up other things - I believe there have been some actual banners printed up for display at car shows, and other merchandise bearing this logo on it. Change the website and suddenly these items become a little out of place.
RE: the fordscript looking bad, that isn't really true - it's just what's been with it. Plain white text with a black surround.. on top of a darkish background isn't the most inspiring thing in the world.
When updating xFalcon a few months back this is what I came up with for some banner variants:
Still only using Fordscript.ttf with some effects.
However I do think updating the FFau banner wouldn't be as easy due to what I mentioned above..
