Slightly off-topic, I think the only proper way to do Aikido demos (such as Aiki Expo) is by having ukes from OTHER SCHOOLS.
This will really make people prepare for this and the difference in skill will be a lot more visible.
Someone else came up with this idea first, I know it. Too bad no one is implementing it.
Also, no pre-programmed sequences of attacks in jiyu-waza demos.
