Latios|Modest|31/31/26-27/31/28-29/31
What do you guys think?
1. Modest makes the 31 in Atk worthless, which means that you basically only have three flawless stats. Since every single Gen VI Latios has three 31s by default, that's pretty bad.
2. Speed-boosting natures are (usually) better on a Pokémon with a base Speed of 110.
3. Toss.
