Plunkett or Anderson? Or both?

Liam Plunkett, James Anderson...or both? That is the question Scyld Berry attempts to answer in his article at the Daily Telegraph, as England's selectors deliberate who to pick for the tour to India:

If England are to play to their strength, and field four fast bowlers in these first two Tests, will Liam Plunkett be sufficient as the only back-up?

He has surely taken over the No 5 spot because he has a wonderful temperament for a 20-year-old and he can bat. But is there space also for James Anderson, who is getting his rhythm back, and, if one of the Big Four dropped out before Mohali, would probably bowl better than Plunkett because he can swing the ball more?
