Fingers cross they don't introduce brand new balls with different properties for the championship eliminations again...

What tread were you using on the plaction wheels? I'd avoid roughtop and go for a smoother tread.

Who'd have thought having a fast moving rough piece of plastic pressed up against a thin plastic coating on a foam ball would do damage?!?

After playing with the ball for a few minutes, I have very little interest in trying to shoot it using a spinning wheel. It's not that type of ball.

However, building a medieval siege engine (catapult) looks like a neat plan!

I think that there are good qualities to both methods, but I think I would still rather have a flywheel shooter because it's more accurate. I may be wrong, though. Also, I'm sure that there will be replacement balls available between matches.

Look at Team 16's catapult from 2012.

One thing about using a shooter is that it kind of tears up balls, which is the subject of this thread...and the balls cost a lot. I don't think our team can afford to test and tune a shooter this year!

Has FIRST been able to offer a good reason WHY basic foam balls are priced so highly?

We couldn’t find less expensive alternatives that had all the characteristics we were looking for, like being foam (so we didn’t need to worry about inflation levels or popped pieces), having some level of durability (though spinning shooters will put them to the test), being the right size, and, very importantly, being low bounce (to minimize the chance of boulders bouncing somewhere you really don’t want them to go). Hopefully, you won’t need as many of them as you did for a game like Rebound Rumble, in which you could carry several game pieces without penalty.

Not so basic. They had a lot of criteria to hold.

Hm. It just seems like a foam ball, even built to specifications, shouldn't be quite that pricey, although as always I appreciate the thought from FIRST that went into the game piece even when it seems basic!

I have a feeling that this is what the GDC wanted you to feel. It was no coincidence that from the material down to the name of the game piece it automatically scream catapult.

Well...
BALLISTA FOR THE WIN

Maybe.

Anyways, had to stop a rookie from picking at the skin of our boulder... It seems heavier than it looks.
