I think the best is Whirl of Rage--->Quadrastrike-->Goblin Rush-->Amorphic Spikes--->Quad. Continuum--->Bloodrake.
That said, actually getting that off can be a pain and you do have to set a lot of spells that you wouldn't otherwise. For that reason, sometimes either spamming Glutinous Dart or combining Azure Lore with Unbridled Wisdom and spamming Bloodrake is the better option.
