I don't know about other people, but for Defog Latios, the set i use is this
Latios @Leftovers
Trait: Levitate
Evs: 4 HP/ 252 SpA/ 252 Spe
Timid Nature
- Surf
- Dragon Pulse
- Psyshock
- Defog
Ofc, you can always run whatever that bulky latios set was last generation or just use bulky latias. Your call, but i prefer latios
