Scurrius AFK Guthans NO BLOODFURY (22kph) 

Ditched the bloodfury, used amulet of the damned. Swapped the infernal cape for hp cape for more regen.
Takeaway: You do NOT need a blood fury. An amulet of the damned, SGS, and using the cheese as needed is sufficient. The difference in APM is so slight I do not think the cost of the bloodfury provides any meaningful change. I do not think the hp cape was even worth it and will be switching back to the infernal cape.
If not using the bloodfury this method is essentially breakeven.
