Although the battlefield may generally have revolved around the lances of the men-at-arms, and the missiles and polearms of the infantry, the sword was the primary weapon of the knight for individual combat. Which is what the arena focuses on, so I'd rather keep to a sword. Not many duels I know of took place using lances anyway. (aside from jousting tournament, but their less about duels of honor)    

In the same way the Katana and such are the weapons for individual duels for Samurai.

You're right, in a dueling sense it makes sense for a Knight character to fight on foot with a sword, unless he was conducting a joust or in combat with an opponent he was under obligation to kill under any circumstance, such as any person he considers infidel.
