I played .09, Diablo_dude, but back then the best dueling skill for Barbs was whirlwind. I'm pretty sure that goes for .10 as well. After you get that, you can play with the other skills. I usually liked to have a lot of run/walk as well, so maybe a little bit in that. Get good resistances. Get the attack that adds elemental damage (you can get it at level 30, unfortunately I don't remember the name). Max whirlwind, and a weapon mastery though.
