How is the exit row seat padding on the 739s? Looking at a couple of flights next May that are currently scheduled for 739s, and I seem to recall comments about exit row padding being worse that other E+ seats. 7EF would be my preference but I'm hesitant to snag 7F for one of us and then we end up not getting exit row seats together if E doesn't become available at check-in. Exit row pitch is hard to beat on the 739.
