We need Ishant and Zaheer. Else our fast bowling attack looks toothless. RP can only pull it off on helpful pitches.
It is not a coincidence either, RP Singh simply lacks the consistency to probe away at a good line and length on flat pitches. I don't think that Zaheer is the solution to India's problems as he is not so flash on flat pitches either, but he is certainly a step up from these two.
News is that Ishant is declared fit for the second Test. Who, out of RP, Sreesanth, Praveen Kumar, VRV Singh or Irfan Pathan, gets the other place is anyone's guess.
