I know TRTGI is a single for some strange reason but I would replace it with either 44 minutes or Endgame. That's really the only change i'd make to the set.
All the old stuff except for most of RIP has been played to death live. But the songs always work well when you see them so there's no reason to change it up too much. RIP in full should be enough to satisfy everyone anyways.
