don't discount bar width. having your hands spread too wide or narrow can strain the shoulder and arms.
hold up the ends of your bars up to the bony protrusions on the front/top of your shoulders. the ends should rest directly on them, or at most 1 cm wider.
I feel most comfortable on a 380mm bar, but 400mm feels almost as good. Anything more/less hurts.
