As for my World Cup 20/20 first choice side on the proviso Starc, Cummins, Patto and Finch are all injured and unavailable, I'd go with:
1. Khawaja ( he's just on another level right now and is so perfectly suited to slow wickets with his wristiness)
2. Warner (picks himself)
3. Watson (for whatever reason he only makes runs in the top three and he can't run between wickets so he is wasted coming in at the death. He is also our only decent seam bowler available)
4. Smith (c) (picks himself)
5. Maxwell (picks himself, plus another spin option on those wickets is vital)
6. Head ( controversial I'm sure but as much as I love Lynn, his glaring hitting weakness is against spin, makes him kind of out of the picture in a subcontinent World Cup, plus ahead is a more than handy spin option who has a happy knack of picking up wickets)
7. Handscomb (I'm not sold on Wade at this level and you need a keeper who is quality behind the stumps in this format, kind of rules out all the other options but Nevill and he is not so good at this format. Plus Handscomb is a gun in waiting)
8. Faulkner (Just hope his form picks up because he could be a major trump card)
9. Boyce (Showed what he has got and it is impressive, could be deadly on the subcontinent)
10. Hogg (We aren't building for the future here and he is a rare commodity, a left-arm wristy with a deadly wrong-un and a sublimely better fieldsman than what the men half his age have shown in this series)
11. Coulter-Nile (He is the best of a bad second-rate bunch available and he is more than handy as a late innings hitter as well. If he's out, Tait because at least he has pace despite nothing else and that is precisely what all the other options have - nothing)
