Kaino should win IMO - he's been the most consistent this year of the lot.
Weepu only really blew into form in the QF, I'm actually surprised he's there at all, especially ahead of some of the Welsh players. Nonu has also been a little hot and cold going through the leadup to, and pools stages of the WC.
Had the Aus pack been performing better, Genia and Pocock would've looked even better and been in with more of a shot, but I can't see it happening - no offence to them and certainly no objection to them being there.
Dusautoir almost seems like a pity pick as, IMO, he's been outperformed by both of his current loose trio teammates - Bonnair and Hardoniquay.
Would've liked to see one or two Welsh here as they've been fantastic - Jamie Roberts and Sam Warburton especially (prior to his red card though I guess).
