Well, I think my proposed First XI is the same as yours, with the only question being between McDonald and White - a decision which would probably be made on the basis of the type of wicket being played on as much as anything:

Phil Hughes
Ryan Broad
Shaun Marsh
George Bailey
Luke Pomersbach
Cameron White
Luke Ronchi
Beau Casson
Peter Siddle
Steve Magoffin
Doug Bollinger

Broad
Hughes
Marsh
Bailey
Pomersbach
Ronchi
McDonald/White
Casson
Magoffin
Siddle
Bollinger

If there's a question over Voges being in the squad, that's another matter. As for the reserve keeper, I'm not particularly fussed, but Rachael presented some quite compelling written material regarding his keeping ability whilst someone (maybe Aurelius) suggested Manou wasn't much kop.
