This is a build I've been considering for a while:
Strength: 27
Agility: 12
Skills to attributes: 8
Power Strike: 9
Athletics: 4
Power Throw: 6
Weapon Master: 4
One Handed: 111
Throwing: 98
(I'm actually not sure if you can have 6 PT with just 98 throwing. Anybody know?)
12 throwing spears + Iberian mace or military cleaver.
Alternatively, you could go 2h and roll with the mace. 30b with 2h animations and 9 PS should be able to put most opponents down.
