Sugestions for the third petFollow

I currently have a boar and he is great for PvE, and atleast he was great for offtanking. The second pet is an owl mainly for PvP and I don;t know why i like it so much :P

And the third is the black lion Humar but only lvl 33. I like him because he is something not many hunter have, but it's boring to lvl him to 60. I was thinking of getting a Son of Hakkar. Many hunter say it is the best for PvP. I was wondering how much does lighting breath do if the hunter has about 1k AP.
