SO im doing the companions questline but... i feel really uneasy that i have to become a werewolf. I prefer sovengarde obviously

Any tips on how to RP as a nord?

It's all up to your character,you don't have to become a werewolf.
Walk away and never look back knowing you will be going to sovengarde one day.

i mean i could cure myself when the chance arrives but, i want to get nord hero weapons/wuthrad/shield of ysgramor.

When in the questline do you get to find out about the Sovngarde issue? If it's later, your character wouldn't know becoming a werewolf prevents him from having a Sovngarde afterlife.

good point! it is later

RP as an http://www.imperial-library.info/content/ages-man who can do whatever he wants. And then use the pickpocket glitch to keep the Jagged Crown. And wear that with Dragonbone Plate Armor and cast the Master Dragonhide spell on top of it. LMAO. It's what I do.

When RPing you have to keep in mind that you may know the outcome but your character doesn't. When your character finds out, then there is the cure option that comes up later. Just use that.

RFLOL you can cure yourself later in the game. So be a big bad werewolf and have some fun. When you get tired of it cure yourself= Then off to sovengaurd for you...
Now RP I find if I talk with certain charaters they are looking into a cure right before you even become one. So HINT HINT HINT...
