Beyblade Larp event - need ideas.

So, I happen to run a Live Action Roleplaying Game in Maine.   Mostly its about hitting people with foam swords and shooting nerf blasters, but it is also sometimes about beyblades (aka spinblades).   I wanted a hobby that game characters would be into that wasn't something people were very familiar with in real life (usually). 

You can see some blades in action in this video:   

Currently I'm trying to put together a sort of tournament/adventure/obstacle course using beyblades - with various challenges the players would have to complete with their blades, like balancing it on the top of a post, or battling an unusual blade opponent, or an unusual arena.

If anyone has any ideas for good beyblade challenges I'd love to hear them!
