Well, actually if you really want to use a bastard sword I'd completely forget about fighting onehanded. It has same damage as your standard onehander, but like 30% less speed just for 10 extra reach or so. Better idea: Carry a 2h sword, a shield and a long dagger with something like Dravics build (I personally don't like converting for shielder though, rather buy more shield and IF). This dagger isn't only for style, with shield it can work wonders vs light armored archers.
