Saw this product appear in my Facebook feed today. Local product, not available for HD yet but thought it looked interesting. Sorry if it has already been discussed.

I was thinking of one for my XR. They are dear I know but the sideways movement (which you don't get on a paddock stand) make them pretty good particularly on rough concrete or a pebble driveway like I have. I have tried a couple of bike skates (and changed to better castors) but they don't move that well in the conditions I have.
