My concerns for NZ are that McCullum is not good enough to be batting at number 3 in a Test side. He should be allowed to come in at 5/6, hopefully when the ball is an older state, and play his attacking brand of batting. He should be restricted in his strokeplay, and the responsibilities he will feel at 3 may see him a little more cautious than usual.
Dan Vettori should no higher than 7, I appreciate he is probably a better batter than I give him credit for, his style is pretty ugly to watch, but I understand he can be effective, and at 7 he will give the line-up a degree of batting depth. If he were to bat at 6 with Hopkins at 7, it looks pretty weak.
I hope they don't fall into the trap of feeling like two spinners are essential in India. Yes conditions may indicate turn will be a prevalent factor in winning Test matches there, but only if the spinners are of a high quality. India play spin exceptionally well in their own conditions, the way they toyed with Hauritz, the latest example of this. I've seen in England do it in the past with poor results, they felt obliged to play spinners for the sake of it, India will dismantle most spinners. It is not easy even for the spinners to contain India. Australia hoped Hauritz would at least do that even if he wasn't a wicket-taking threat, and they could attack with Hilfenhaus or Johnson at the other end.
The way NZ are going to trouble India is if they have a bowler or two that can find some reverse swing. Zaheer Khan is the perfect exponent of this. Basically he'll have a go with the new ball, they'll then employ the spinners till about 45 overs when Zaheer will return, generally to good effect, and get in reversing. Who are the likely bowlers in the NZ squad capable of achieving this ?
