These are pretty good! I didn't like my chances of getting this right so I decided to film the whole thing from 3rd to 4th contact instead. The result (at 4x speed) is

You can see that the seeing came and went but was pretty poor throughout. I also had to yank the mount a bit to keep the action centred…
Cheers
