I've been doing some research, and it seems that the ping pong ball has yielded the best results as a projectile. Would you agree?
What I have observed from teams at Nationals was that Ping Pong balls were the most common for the simple reason that they are the only plastic ball that will fit 1 1/2 in PVC. Finding PVC for plastic golf balls and the other balls is extremely difficult. unless you have found it, go with ping pong ball.
Ok. Thanks for the tip!

Really depends on the kind of wood you're getting. The "good looking" wood is not surprisingly going to cost you a lot more (sometimes making your project cost 5 times more). If you're on a budget, as a lot of students are (and it really doesn't have to look beautiful to win), some home improvement or lumber stores sell scrap/damaged wood for less; I think I've seen it at 70% off sometimes. If your device ends up being a bit wobbly, add some metal brackets or add some wood supports to your angles.

I don't really care if my trebuchet is pretty, so I will probably buy the "not-pretty" wood.
