I agree that the blue wizard hat is really cool, and I use it a lot for single player, but I find that using the nitro ball in multi player (race mode) is a bit iffy. Sometimes the game lags so much, your nitro boost doesn't even do anything! That's why I don't use the blue wizard hat in multiplayer, but rather the sticky toque hat. I've often trolled people with this hat (good times) ... People who don't use the sticky toque just sit on the green waiting for their character to come up. While they're waiting, I just come up from behind, stick immediately to the green, and putt right in!!
