I put L at 10 because he seemed like the only option if Quade has been dropped. I actually have concerns about Christian at Super level let alone test match level. So if Quade comes in I would drop L altogether. And no I can't spell his name!
On a serious note I really reckon Aussie needs a game breaker at either 12 or 13 and I reckon O'connor is one of the better players on the planet.
