None of the wrist primer videos talk about the slightly ulnar form explicitly, except to say that you want some of that. Why is it needed? What happens if you dial it out? Some of the example player seems to have more or less of it, is that just due to different morphology?
From the videos I got the impression that this slightly ulnar form is the ‘sweet spot’ where the wrist deviation motion is most efficient / effortless, given the anchor points. Is this a case where the proof is in the pudding, in the sense that if you can do a fast and smooth motion, with the right anchor points, then you’re also the right amount of ulnar (given your own morphology)?
