Karthik as a Test bowler is a waste of time that too against Pakistan.. Munaaf is a good choice, probably the only choice if India play only 2 fast bowlers. The only chance Pathan has to get into the squad is if India play 5 bowlers which they won't. Sachin and Saurav will be the 5th bowler and Kumble will have to bowl a lot of overs.
Dada in short 4 over spells can ease a lot of burden.
