I would have the inputs lined up for corn or beans . Keep and eye on the wheat and save the very best fields. The rest I would make the call after the other corn and beans have been planted.Doesn't make me very happy when we have killed a field of wheat and the weather turns against you for corn or beans.
  Or you can lock in a price for your wheat. That will make the decision for you.  Same with corn or beans.

    Have a good winter.
