Here's why I like the blade spoiler. It really looks like not an afterthought, like the RS spoiler.... the RS looks small and looks tacked on to the trunk
And here's the blade and look how it covers the whole back of the car. to me it looks like it was designed for the car. The part of the bumper right above the license plate vsually pushes out strongly, and the blade balances it more.
And on the SS, it just looks way better, IMO.
