How should I hold my foot in natarajasana/ baby dancer pose?

I've heard people say that you should always hold your foot in a certain way in dancer pose. And I've heard other people say the same thing, but about a different way of holding it! My view is that, as with everything with the body, it depends on what you are trying to achieve and how it feels when you try it. This quick video talks through the different ways you might or might not hold your foot, and considerations for each of them. Note that this video discusses the version of dancer where you are reaching one arm back to hold a foot, not the arm overhead version.
