Brilliant 2U Orchestra Groove Oni is so much fun when you finally learn how to do it without the double-stepping! Same goes for Übertreffen, it's the main fun of those songs!
people ask if I could do the spins in Brilliant 2U Orchestra Challenge... there's no spins in that song, anywhere. It's all 270 degree turns, but most people will double step that because they don't want to have to try to turn away from the screen (which is fine).
My buddies and I call those reverse crossovers because, well, they're crossovers that make you reverse around and face away from the screen.
And I agree. A LOT of people get these confused with regular spins.
Btw, if you have access to DDR Extreme, Butterfly on Heavy is a GREAT song to learn spins on. Lots of RDLU spins in there.
