Now, clearly, what they can do is largely facilitated by the rules. You wouldn't see the same interaction if the opponent was a boxer (entirely different entries, which changes the opportunities). Might see about half of the same if the opponent were a Judo player.
If there was a Tomiki Aikido dojo locally, I would love to check it out. Unfortunately there don't appear to be any in Kentucky.
