Go to solitude, go to the shooting range. Pickpocket the one who is shooting and plant 1 arrow of your choice on to him. Wait for him to go to his bed and pickpocket his arrows (all). Wait til the next day and he will be shooting your arrows of choice.
Did you read my post at all?
And thanks Vermilion, I'll check both of those out. Also, quick question, since most of the damage from archery comes from your enchants, is the type of arrow/bow you use a big deal? I've been meaning to test it out but have yet to get around to it.
Basically, could I use an Elven bow with iron arrows and still get close to the damage output of Daedric bow with Daedric arrows?
