I do have a question about the classic controller. The L and R button isn't sensitive like the GC's right? (I don't know the correct term) but like you can push it lightly down and the shield would be big. And what about short jumps does it work like the GC's controller?

From the IGN podcast (sorry I don't have a link), the people say that one of the many things from melee that have been removed in brawl, is the varying sizes of shilds depending on how hard one pushes on the button (even with the GameCube controller). Don't know about short jumps though.
