The fact is, imho, that a lot of songs of HTDAAB are better live than the three previous records. Vertigo, COBL, Sometimes, Miracle Drug, ABOY and - amazingly - LAPOE are magic live. It gave me more thrills than Stuck, Kite, BD or In a little while... So it will be difficult for them to choose. Perhaps Bullet will be dropped in favour of LAPOE and Elevation replaced by Vertigo; COBL will make it to the set most of the nights.
However, it will be difficult to remove Bullet. As a non-hit-single, they've played it at nearly every gig since the JT-tour... It's a bit out of date, but they can't get enough of that song. Neither can I.
