Linear Path Shooter vs. Circular Path Shooter?

[Robogineer1649]

We built a prototype and it had two parallel wheels as you were saying you might try. I must add that it was in a linear fashion. But what i really want to tell you is that the frisbees go much further if one side is stationary compared to both sides spinning. Additionally our team has not tried to make a half circle shooter design only a linear so i can not take about that aspect of your question. What i can ask you is why would you use a half circle shooter that takes up much more space especially this year with smaller robots rather then building a linear shooter that works just as well?
