Found a really great YouTube clip making clear what I’ve long suspected but didn’t really have a great view of, which is Clint Strong’s double escape wrist motion. Here’s the “audience perspective” view we get on his REH instructional, along with the strings perspective from the YouTube clip:
What you’ll notice is how decidedly non-bouncy this looks. You would not look at the REH footage, or really even the YT footage and think, this guy is making a wrist motion that goes up and down as it moves side to side. And that’s the trick. If you’re working on this type of wrist motion, and you can even see it at all at normal speed, it might not be right. This is especially true if it feels bouncy, or tensiony, and you sense any kind of hard speed limit. When done correctly, there’s no feeling of doing anything “extra” to achieve the double escape compared to doing a single escape motion.
