Question about WW barbs.

[Knighty]

Hi, I haven't ever played a WW Barb in D2 before, and a buddy linked me a build.

20 Mastery
20 WW
20 BO
20 Shout

Then the remaining goes into other things.

My question is related to what Mastery I should go. My friend recommended either Swords or a Polearm, but wouldn't two 2H swords be far more effective than a Polearm ever would? He also mentioned something about them being interchangeable, no idea what he's talking about there.

Thanks for any help.
