i think the commodore is pretty much already equipped for surround sound. they certainly have PAs in the right spots, except maybe the rear. thats my best guess for vancouver. likely hte best spot would be in the middle of the floor just take note of the PAs hangning on the support beans along the dancefloor. that's the "sweet spot". not a bad place to tape from, but also a place where all the talkers hang oout. and when the crowd gets bored, they'll chirp.
