I think selection is ok.Last VB series Malinga played only as the super sub.We don't need 2 specialist spinners.We have Sanath & Dilshan.In Australia we have to go with 3 or 4 fast bowlers.Also can you remember what happened to Malinga in last series (Sharja) and how Pakistan players treat him. Tharanga is out of form but he has proved what he can do in the history. So I don't think there is better choice. There are players who performed in domestic cricket well but we can't put them to a taugh series like this straiter way since the gap between our domestic cricket and International is very wide. Indian,Pakistan,Englan or Australin players will do it because their 1st class cricket standard is very high.
