I've seen the Aussie Floyd everytime they've been here for the last 5 years :D.
They put on a cracking show, the lasers and everything as I'm sure you're aware are top notch. I seen them do The Wall this year also, it was a great show for me, because they normally leave off a few of my favourites from that album off their set.
However my favourite show of theirs was the one before this, they had an awesome setlist, which was basically a greatest hits, and then Dark Side, followed by Numb and Run Like Hell.
I'll go every time they're here, great experience! and about as close as I'll get to seeing Floyd unfortunately. :(
EDIT: Actually the best moment for me ever seeing them was 2 or 3 years ago when they played Echoes!
