Which team in IPL4 show a great bowling performance?

As I observed Chennai Super Kings have better bowling prowess. They have the batting skills also. Mumbai Indians have the bowling strength, but can be ranked next to CSK. But MI is doing fine due to its strength in batting. As at present in my opinion these two teams only stand chance to become the IPL4 champs.

somehow i feel kochi bowlers have done exceedingly well throughout the tournament. R P Singh is in awesome form and i think he might be rewarded by his come back in the indian team in the absence of zaheer for WI series.Shreesanth and Ravindra Jadeja too have done descent job.Its their batting who had failed on numerous occasion and let them down.So for me Kochi Tuskers have shown the best bowling performance till this point of time.Mumbai indians too are going neck to neck because of likes of Mallinga and co. Regards. Keep mylotting. :D

i think mumbai indians.
