Well, if we could pick our own "ideal" scenario, mine would be:
Do a 6-song I&W suite, with two alternate set:
1. PMU, TTT, Metropolis, Another Day, WFS, LTL
2. PMU, TTT, UAGM, Surrounded, WFS, LTL
Then do 2 FII sets that are each half of the album, and rotate those. That way, all of I&W and all of FII get played over the course of every two nights, and there is still room in the set for other stuff.
But I can tell you, they aren't doing that.
