The reason we probably need 2 up top at the moment is that we don't have an "all-rounder" of a striker at the club (the last being Ciftci) that can play a lone striker comfortably.

Based on what we've got available I'd say (certainly for home games we expect to win) we should be playing N'koyi, for his physical and aerial presence, along with either McDonald or Keatings. This then leaves us with a quality striking option off the bench.
