Wouldn't Set A_V5 just likely be replacing V4 at this point? It's just one extra song that makes it different.
And still no setlist, but ending with APFMH is not a good idea. It would be great while the song is going, but as it ends, it just abruptly goes out, like Astat was saying, even with a longer outro. I'm still a fan of BIO or OSC closing, largely for the fact that they have the droning guitars at the end so you don't end the concert in awkward silence. APFMH would need pyro or some really good modifications to the outro to serve as the final song.
And Mike's instagram video looks like they ended with BIO with the sustained guitar feedback playing. I could be wrong, but it wasn't APFMH tonight,
