[Matt Gent]

-a catapult design does not have to come to a sudden stop
-the energy stored in the arm's rotational motion doesn't have to be lost (it can be restored into its original form)
-an effective & accurate catapult can be made that is not a trebuchet (ie doesn't use weight @ height to store energy or an arm/sling)
-trajectory could be changed in-match, but it becomes complicated. With an intelligently selected single trajectory it is possible to score at a wide range of distances from the center goal.
-a catapult can be implemented with a rate of fire of > 1 ball/sec
-a clutch or similar device is not necessary to "k"ock the mechanism when driven by a motor
-a working prototype using a whammo-type jai-alai cesta achieved much greater than 12m/s and has many variables for adjustability.
