Lv Cap reached

Sky and MetalSound are Lv 100! I still have movesets to worry over though.
There's Fly vs Aerial Ace on my Staraptor.
Both are flying type moves. Fly has a higher base attack with 90 but 95% accuracy. Aerial Ace only has 60 for its base attack but it never misses unless the obvious. Fly is no good against a Machamp with No guard for it's ability and Stone edge, which is where Aerial Ace comes in, but I can't always rely on Aerial Ace for OHKOs on type advantages, (for no apparent reason every HP counts, and I hate focus sash when it's used againts me!)
I can't get rid of the other two moves which is Defog (for double battles when I'm setting up for a move like Gunk Shot) and Close Combat (pesky Rock types and Ice types).
Maybe if instead of Sky plate, the item is a Sitrus berry, or the sort, I could ditch Fly for Mud slap. But for a move with only 20 base power? Maybe as a set up for Close Combat. If he gets paralyzed then maybe he should hold a Cheri berry.

And there you go, I am speaking Pokemon Lingo.
I'm heading over to Smogon!
