In response to the bouncy question above.

I had a chance to visit the HOT (67) teams field and bounce a game basketball off their backboards. I concluded very quickly that a hard thrown basketball without some kind of ball spin would have the ball "bounce back" hence my term bouncy used above. I am sure teams that constructed practice game fields made a similiar conclusion early in the season.

There are other discussion threads related to ball spin that you may want to read if you need to read up on ball "back spin". We intend to have the upper set of wheels spin at a different rate to induce back spin.

I am wondering what other team's ball spin speed ratio has been experimentally determined to provide "adequate" back spin.
