you can't be sure that 100% of the teams are going to be able to fire straight up, there are alot of teams with gravity feeds.
I am personally a fan of the radar gun. We had an officer come in and test ours yesterday and it seemed fairly accurate based on our calculations. The main thing is FIRST just needs to make it a standard for each comp. If a radar gun is used the same person set up in the same way for every team, so even if the gun is off everyone will be on the same playing field.
I was also thinking maybe we could make a custom poof ball with a build in accelerometer and a tiny micro processor. Then the teams would have to shoot that ball and whatever it says goes. just like these for baseballs.

Now that i think about it i might go buy one of those baseballs and transplant it into a poof ball to see how it works.
