Bottom line(s): - Get an 11" ball, not a 12" or larger.
- If Worth makes only one ball that matches the vague spec in the FVC BoM, it isn't obvious on the Worth web site.
- Cross your fingers and don't spend too much money just yet...(I haven't opened my $50 bucket of balls yet.)
- I think the Hangin' Around BoM needs a bit of improvement (Such as a more precise ball spec or an explicit confirmation that the vagueness is intentional).

Thanks Blake,
My main concerns were mass, there weren't any weights listed on the packaging, and the composition differences between slow and fast pitch balls. I'm sure it's an issue of energy transfer. Slow pitch balls are probably slightly "harder" so they preform similarly to fast pitch balls which are being thrown with higher energy. Slow pitch balls will transfer energy a little better than fast pitch balls. In this game it shouldn't matter, other than if there had been a weight difference.
The other factor that might be important to some teams would be color. The manual references the high visibility yellow balls, not white. If a team wants to use a light sensor to key in on the balls, there would be a difference in signal between white and yellow balls, and it would also allow contrast between the white field lines and the balls.
I'll also agree that this year's game is great!!! Thanks GDC!!
I'm always a fan of large size scoring pieces for vex. That atlas ball is even bigger than I'd expect. Very cool.
