The best way to select a team is to think the composition. Move Dhoni to top, keep sehwag at 6
remove raina Dinesh Mongia from the team, and keep trying a bowler like Harbhajan or Zaheer in the middle of the innings like 30th over, where he they can just disturb the rythm of the part time bowlers with some slogging. though thy dont make 50's but 15-20 runs from their bat should be useful
