I go adamant max attack and hp brave bird. Max damage is my preference plus priority roost when/if you get the chance lets it drop a few more brave birds.. I haven't used acrobatics but I imagine it can be just fine too
Acrobatics is automatically bad ebcause you can't use it with Life Orb or Choice Band like Brave Bird. Maybe if you're running a gimmicky Nature's Gift set after you use up your berry, but otherwise, lolno. Brave Bird it up.
