SLX rotors? Problem solved =)

I got a pair of SLX brakes for Chrstmas and I thought that I could keep the 160mm rotors from my Hayes MX4's, but the mechanic says that the callipers are not sitting where they should be and for them to work at their full potential I need Shimano rotors that are fitted to spiders rather than being cut from the one shet of metal.

Anyone have any ideas as to what rotors I need then? They would have to be 160mm and fit a 6-bolt XT hub.

Would it be either of these?
