that sounds similar to where we play. Our court has walls on all four sides so you can really play off the walls well. We found a great new court but their are freaking little hockey players play hockey on our newfound 'polo' court, we'll have to remedy that somehow.

What you guys need is a really hard ball, we've been using the hot weather hockey ball this winter so it's rock solid and will bounce off the walls really well, improves the play a lot. Just be careful though, because it's solid as a rock, it'll hurt like hell when you take a shot to the body.... hurt A LOT!!!
