It would have been a great idea had India kept Harbhajan for the tests. I see no point in playing three spinners and two fast bowlers when SA can easily play the fast bowling. India should use their strength and play with four spinners and one fast bowler. Four spinners should be Ashwin, Harbhajan, Jadeja, and Mishra. SA players were brought up on pitches conducive to fast bowling so they don't have issues with our fast bowlers and especially because their line and lengths are just horrendous. If SA can play against four quality spinners and win a test match in India then I could say that they are a real quality side.
