I think the answer depends on which climbs you're planning on doing.
2 or 3 finger-sized cams are handy on Brolga. Now's the time to point out that finger-sized might refer to the x or y directions. I mean both. Friend 00 to green or maybe yellow Alien in my case.
Skink is easily done with a standard rack, including a set of wires. Take a bolt plate.
Auto Da Fe needs some small wires and doubles of cams in the small-medium range.
The Confession has basically no gear up the corner, so it doesn't matter what you carry.
