it depends on the time. Generally the temperature is more equatorial in the south.. Chennai's coldest tends to be around 20 degrees in celsius scale.. That is considered HOT in England, I believe..
And yeah, the Kiwis are a good one day unit too but honestly, if the matches were held in Australia or so, I would be backing India more than the Kiwis.. In their conditions though, I do think they deserve to go in as favourites..
Also, they seem to have found two very good batsmen for nos. 4 and 5... Taylor and Elliott really impressed me in the CH series.. I think both will be very very good batsmen for New Zealand in years to come... If only they can sort out and get the best out of the likes of Fulton and Ryder...
