Korean Air Skypass - First flight on KE 747 - Which seatmap is the right one?

I am flying ORD-ICN in July in Prestige Class. I can see from the KE website that the aircraft is a 747-400, but when I go to SeatGuru to look for advice on the best seat to pick, there are 4 different seatmaps. Does anyone know what the configuration is for the ORD flight? Or alternatively, could anyone suggest what the best seating choice might be? Thanks in advance...

Looks to me they use the 747 with the first class sleeper seats on the ORD-ICN flights. So most likely this is your configuration for your flight: http://www.seatguru.com/airlines/Korean_Air/Korean_Air_Boeing_747-400_B.php
