Well, are you talking about duels or in general?

For duels, yea, eagle definently. Basically beacuse it is a LOT faster. Speed means a lot. And, it does decent damage. Plus, because of the guided peirce zon buriza isn't really legit. But, yea, eagle shoots a ton faster than buriza so I suggest that.

BUT, for PvM, I would say buriza. It does more damage and has peirce and has tons of cold damage...thats really good versus cows.
