Competitive Victory Valkrie

What are some competitive VV combos
V2.T.Z (when metal lines up with the contact points it's Impact mode, if it lines up with the wings it's in Rush mode)
V2.L.U
V2.B.Q (more of a fun combo)
V2.H/G/K.X
Victory Valkryie feels very tight (hard to burst) with the Knuckle disk. So I feel Victory Valkryie Knuckle Xtreme would be very good. Accel or Zephyr would also be good.
