Babolat Duralast "Nadals String"

Does anyone use this string here? If so have you ever used the Hurricane and could you tell a little about the difference between them. Also, if you aren't familiar with this string you can find them on that little auction site. You can obviously tell that the Duralast is what he's playing with if you look closely at pictures, they are transparent and Hurricane's are not.
