I am hybrid archer/2her, with a +1 heavy bastard sword and medium armor (when i feel archer i go leather armor, when i feel meleeing, change to byrnie or even banded armor) and my final build will be:

I only use 1 stack of tatar arrows, but with aiming and patience i rarely run out of them, unless on EU 1, but then i loot (or melee).
