I like scoops on all Imprezas. Heck, my OBS comes stock with a scoop and is NA... so is that really rice? It's basically the same thing.
As far as the STi wing... hell no. That's rice. It's way too big for the stock 2.5i suspension and wheels. It looks goofy. It even looks boardline goofy on the STi. Wingless or the little spoiler on the GD IMO.
