Don't listen to him about the bi-directional, they're fuckin awesome.
I do, however, recommend a glaive or poleaxe for your build though. Swiss and Bill are a support role weapon, kind of like a long spear / pike deal, but you have the full ability to go 1v1, so long as you're agile enough to make your opponent miss an up or down block. The poleaxes are fully functional beasts of weapons capable of high pierce thrusts on top of high cut / shield break swings. Regular Pole is slowest and longest, German's the most powerful, and Elegant is quick, plays almost like a 2Her.
Consider a Long or Great Long Bardiche too, awesome weapons.
