Both guys pretty much play into eachothers hands.... and both have the power the seriously hurt the other. Pav is technically more sound, which is enough to make him a slight favorite... but its basically 50-50 as I see it.
Obviously 168. Froch cant make 160, and Pav is a 168 pounder who shrinks himself down to 160 to pick on smaller men.
I like Kelly, but my pick would be Froch. Too strong and the ****er just won't take 'no' for an answer.
Pavlik has the better skills and stamina, but he gets hit too often to handle someone like Froch at 168. It would become a brawl and that plays straight into Froch's hands. Pavlik would make it a good fight, but my bet would be Froch by TKO.
Both of these fighters are relatively crude with big power . Both have ackward, plodding movements. Froch has the better chin, but Pavlik has the better skillset so I will go with him.
