Well done on the Dagger-throwing
Firefoot. This will make your character, Scyld, stand out more in Scarburg.
Nogrod, for the sack-fight, I think that Erbrand will fair quite badly in it. He's tall and not too flexible, his sense of balance would be completely destroyed due to his height. For the quarterstaff, Erbrand would not have used one for fighting purposes, though I'm sure he could grasp the concept very fast, especially if he watched someone fight first.
I'm really anxious for Erbrand to go up against Crabannan in either the sword fight or the quarterstaff. If you wouldn't mind,
Nogrod, I'd like Erbrand to face Crabannan off in the quarterstaff, seeing as Erbrand would have a better chance with that weapon.
On a scale of 1-10, with 1 being extremely weak and 10 being exceptionally strong, I'll rate the abilities that you wanted: strength= 8, agility= 4; balance= 5.
