There is no way Munaf has a better technique than Kumble or Harbhajan. Nevertheless, he does have striking power and hopefully he can do some damage with the bat for India in the near future.
Oh yeah, you should give it up with Pravin Kumar for now, the guy is far from a national call-up. He doesn't seem to be pacy so he'll have to grind his way through. Let's wait to see how he does in the Challenger Trophy against the best of the best and then make an assessment. The guy has just done well for a few months.
