I am in my fifth year of competing (three in high school two in college and continuing). I am huge on organization. Organization always breeds a good debate. I normally look to clash when I decide who wins a round, so make sure to spend time on important clash. One oy my major pet peeves is "source" debate. If you ask someone what their source is you better have a dang good reason. Logical argumentation is also something a value highly in any form of debate as anyone should.
