What is the best chao trick in Sonic Adventure 2 Battle

Best Chao Trick Ever:
When you give your chao animals to power up, DON'T just run up to them and give them the animal. INSTEAD... drop the animal just a little bit in front of them. The animal will bounce back, and guess what? You can use it AGAIN! And AGAIN! And AGAIN! Trust me, before you know it, your chao will be maxed out on every level (that's right, lv99!) and you're set to conquer anything that the Chao Races or Karate Competions can throw at you! Pretty nifty cheat, right?
