That was an excellent podcast!
I listened to it from the perspective of being an experienced sea kayaker, experienced WW kayaker, and relatively novice pack rafter. I took a swift water rescue course as part of my WW kayaking training.
I thought that you very clearly and accurately addressed most swift water rescue issues. The only thing that was missing was the key knots and carbineer usage used in rescues. Of course that is not possible to explain in a podcast and so I repeat my assessment - Excellent Podcast.
