Spear for damage dealling and fast killing.
S/S for defence, KD and slow killing
Go Spear for a 2:1 as youll have enough health to back up and knock down isnt really that great from my experience jsut good to piss people off. to sum it up SPEAR.

at lvl 70/80 and farmed youll own anything and everything.
p.s. Make sure you max Soul Spear Soul.
