I don't see the point of using a timid nature on a physical oriented latios. You should use hasty to give your phisical attacks more power.I guess it isn't a big deal, but really the only pokemon I am really worried with this set is Scizor/Gross/Magnezone
And HP Fire ruins them ^_^
Surf is strong, but I just prefer the utility of HP Fire. I believe Pulse/Meteor/Bolt provide enough normal 2HKO or a OHKO for the build.
So I went back through this thread, and I created a new Latios, and it has been working even better.
Mixed Latios (Life Orb) Timid
Outrage
Surf/HP Fire/Dragon Pulse/Thunderbolt
Roost
Earthquake
Also, I don't see many uses of roost, when you lock yourself into outrage you're going to be revenge killed by steels anyway, so you could use that slot for Hp fire\ draco meteor.
