Erica Proud vs. Rolf

[Fishibaron]

Hello all,

Totally new poster here, but I've been playing strong since KB:TL

I've come to a point on Bola Island where I am mid-quest and I have to choose between satisfying the quest-giver "Rolf" (in the barbarian ship on the coastline) or his dissatisfied lover "Erica Proud". Basically, I have to fight one or the other and I'm doing a no-loss run.

The questions are:
1) Which one fights harder?
2) What are the rewards for beating each?

Thanks,
Fishi
