Pick a topic, any topic that you have a very strong opinion on, CA, Plastic Armor, acted wounds, etc... and argue a point from the other side effectively.
For example if you can not stand CA and feel that it should be outlawed, argue how in period, a minor noble may have killed a member of the chiv or royalty with an arrow at least once or some such thing. Or if you love Fiberglass spears what is the worst thing that you have seen/done that makes you quiver about their use.
Remember to argue the point effectively. Making a good point counter to your own thoughts does not reduce the merits of your side. Instead show yourself to be a well-rounded, thoughtful and insightful individual who listens and considers other's opinions and has made an educated decision after understanding the entire issue.
For extra fun, expound the merits of your arch-nemesis on the Armour Archive.
