I think every freestyler more or less repeats the same tricks in every battle. Obviously, if you want to impress the judges, you need to add a few different and more impressive things each round, but it's almost impossible to not repeat some things.
Also, so many of you mention it being a "battle" and you must respond to other freestyler. You make it sound like we are living in a dumb breakdance movie. It's freestyle, and your tricks really have nothing to do with the other freestyler's tricks. It's not like you can defend or do anything to the other freestyler.
