This thread made me smile. Haha, I love silly things like these. ;p Thing is, it is harder to compare two completely different dancing styles. I mean, they're, like, on completely opposite sides of the dancing spectrum. Fi has a more ballet/ice-skating sort of style, whereas Ghirahim does the Angle Dance [not exactly, but we can all admit he's more of a geometry kind of guy being covered in rhombi].
But the Angle Dance is awesome, so I guess I'd go with Ghirahim.
As I told Axle, Zelda is only lying in the middle of the floor, because he did a horrible job at tying her to the ceiling. --He even starts with his knees 45° and does circular spins on his toes! xD How splendid~!
If you don't know what I'm talking about, on April Fool's Day last year, Locke posted this video on Zelda Dungeon's homepage exclaiming a new Skyward Sword trailer.
