This is BW2 - you are not sweeping with 102 speed. The Choice Band set should be the top set as Garchomp is going to be switching in, using a STAB move backed by a lot of attack, and then is switching out again. Now, 10 Defense IVs is a terrible idea. You beat Genesect...and now you're more weak to many physical attackers who can now possibly OHKO like +2 Breloom, CB Terrakion and CB Stoutland. Not to mention random Earthquakes and the like.
The Choice Scarf set is terrible in OU and does not deserve a spot on this analysis, as well as everything else apart from CB and SD. SR Suicide lead and Rocky Helmet go into other options.
