Here's a good example of a soft style aikido.
That's from the Virginia Ki Society. As far as I know, it's about as soft as Aikido gets. If you look at the iriminages they barely touch each other. I practiced at that dojo in the video for about a year or so. It's pretty neat, but honestly I'm a little more addicted to Aikikai style. Of course I'm finding out from this thread, that Aikikai is soft compared to some styles!
Haha!
Here are some more videos. There are a bunch from the Virginia Ki Society towards the bottom.
