Pune's pitch is kind of a flat pitch without much on it for bowler I think which is why India decided to go with 5 bowlers so there could be more bowlers searching for something out of the pitch as all of them have separate strengths. I consider Jadeja a full time batsmen so it's not 6 batsmen I think it's certainly 7 batsmen out of which one is all rounder and not to forget Ashwin can be a great night watchman at times. So India has a lot of batting strength and surely an extra bowler would improve their bowling stats.
I was watching the match on TV, and one of my friends who was sitting besides me commented that there seems to be a lot of grass on the pitch (which we normally don't expect on flat tracks). I am not that knowledgeable and therefore not sure whether he was right or not. But if that is the case, then India made the right decision by going ahead with 3 pacers.
But in case the pitch is offering support for the pacers, then we can expect both Nortje and Philander to perform well tomorrow. They looked dull today, as Kagiso Rabada was the only South African bowler who managed to trouble the Indian batsmen. And Keshav Maharaj had another poor outing. He is proving to be very expensive and the Indians looked very comfortable against him.
and relieved that playing with one less batsman didn't backfire lol
Looks like Fab is having a tough time in winning the tosses, lost all the last six. 
. My advice for the second test is that be cautious as the Pune pitch used to help spinners a lot and then there is the weather issues in the past months that could affect the pitch and i am expecting a spinning track and remember South Africa is not great against spinners and if it is a spinning track then guess what the result could be
