I've played a lot around with it, and found the following opening to be my personal favorite. If you don't have the skill speed to do 9 actions in your berserk, skip Fracture.

Heavy Swing > Brutal Swing >>
Maim (1) >>
Storm's Eye (2) >>
Heavy Swing >>
Skull Sunder (3) > Internal Release >>
Butchers Block (4) > Potion of Strength >>
Heavy Swing > Berserk (5!!) >>
Fell Cleave (Yay!) > Infuriate (5!!) >>
Fell Cleave (Yay!) > Raw Intuition (1) >>
Maim (2) > Vengeance (3) >>
Storm's Eye (4) >>
Fracture >>
Heavy Swing > Brutal Swing >>
Skull Sunder (5!!) >>
Fell Cleave (Yay!) >>
Butchers Block -- Pacified
