You could always do a 2H/Pole hybrid character. Run either with a 2H/Halfsword 2 hander, or carry a 2H for dueling situations and a longer polearm for group situations.
I find halfswording to be a pain in the ass to use for 1v1, but it's really nice when you get in a clusterfuck. polestab animation on a 2H is so hawt in really cramped quarters.
Bamboo spear or long awlpike with a Heavy Bastard sword is a great combo in Battle. If the Pike was still 2 slots I'd be using it with a HBS, unfortunately it got bumped to 3 slots so I have to go with a langes messer instead.
