U-turn is not that great on Specs OR Life Orb. Tornadus-I doesn't have regenerator so you are just wasting health. I'd rather see Rain Dance / Air Slash getting a double slash there. Air Slash is great outside of rain for Specs. U-turn isn't that great at all TBH, most checks can't take a massive Hurricane like that.
