The demo was pretty. Transitions between the roles of Uke and Nage were fluid. Techniques looked pretty and fluid also. The range of techniques shown also gave a great spectrum of Aikido waza. Those were the positives imo.
My other impressions on the demo were already dealt with by Mr. Ledyard and Mr. Janczuk to some extent.
In the end it comes down to what one's goal in training is imo. Aikido as Budo does not suffer effectiveness for grace or vice versa.
