Simon Taufel is pretty good....but he had a big stuff up when giving Dilshan out LBW against NZ on Tues, when the ball was probably going to miss another set of stumps. Rare error from a top ump. The rest of the Aus umps are probably the worst in the world (David, Harper, Hair etc).
The finals should be umpired by Aleem Dhar and Billy Bowden.
Interestingly, the Aus players cannot stand Bowden as he stands up to their antics and imposes himself on the game (much like Hair got up the Pakistani noses in an overbearing officious manner). Bowden remains a pretty good umpire.
