I was lucky to have someone around recently who shot a minute of me riding Sydney. It's not a great video, but it is enough to let me see how much improved I am over the last few years. My upper body is really nice, and I can now see my elbows bending and moving with an elastic connection. My wrists are no longer bent, and my thumbs are on top.
If you watch until 0:51, you'll see a lovely downward transition that shows us both being very balanced in our work.
