Of course I had one idea for this before asking the question! :-)
I'm going to predict that rescue kubbs will start to become more common in 2013. I've yet to see one in a US tournament, even on video and plenty of games have been scored. But we do see them in videos in Europe. I also know that some teams have been practicing the technique and using it very proficiently in Friendly play.
I predict this will be a technique that many teams will work on to have at their disposal.
