What are some competitive VV combos

V2 G/H/7M/7B X/A/Z.

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.
