Wow Derek - thanks for the link. I read that entire blog and watched all the vids. Really nicely done.
I love the first video - the sunny sky, the green water, the mossy round boulders, and the steep banks, and of course some nice looking features. This looks really good. Somehow for class 3, it looks really friendly.
I have a class II+ run very close to my house - the Lower Sultan river. As doing ferries and eddy turns on that become second nature, I'll probably have to nail down a time to try this run.
