sorry to resurrect your resurrection post. You've surely made a decision long ago, and I'm relatively new to HS, so my opinion may be totally off -- but just out of personal interest, my advice if you're not going to get any new terrain is to go with wave 11 and/or Orm. Both would add variety to your situation while staying within the parameters of the set. Orm @ 9 is a particularly good buy.
And, could you tell me where you're seeing these prices, I'd love to drive over!
