Pickpocket deserves a mention, but just mention why it should absolutely never be used, and why doing so will prevent you from getting headaches.
Additionally, please un-bold the set; the other analyses don't do that.
I also agree with Life Orb being the primary item over Choice Band, since Weavile has the potential to become a good cleaner with decent coverage, and being locked into a weak Ice- or Dark-type move isn't that hot when Steel-types can easily switch in and do horrible things later. The boost from Life Orb should also suffice to KO the targets it should be hitting; Tornadus-T dies after Stealth Rock damage and a turn of Life Orb damage from Pursuit, while 252/0 Latios and Latias are pretty much KO'd no matter what. You must mention, however, that these threats can try playing smart by staying in, take a weaker Pursuit, and attempt to damage Weavile in their last moments.
I'll try out Swords Dance, though currently I have a low opinion of it due to its relative reliance on the boost in addition to the threats that can revenge kill it.
